-Generally speaking, the internationalized portion of Xlib (Locale
-Dependent X, LDX) consists of three objects;
-locale (LC) , input method (IM) and output method (OM).
-The LC provides a set of information that depends on user's language
-environment.  The IM manages text inputing, and the OM manages text
-drawing.  Both IM and OM highly depend on LC data.
-</para>
-
-<para>
-In X11R5, there are two sample implementations, Ximp and Xsi, for
-Xlib internationalization.  But in both implementations, IM and OM
-actually refer the private extension of LC.  It breaks coexistence
-of these two sample implementations.  For example, if a user creates
-a new OM for special purpose as a part of Ximp, it will not work with
-Xsi.
-</para>
-
-<para>
-As a solution of this problem, we propose to define the standard
-APIs between these three objects, and define the structure that are
-common to these objects.

-A locale loader is an entry point for locale object, which

+Generally speaking, the internationalized portion of Xlib (Locale
+Dependent X, LDX) consists of three objects;
+locale (LC) , input method (IM) and output method (OM).
+The LC provides a set of information that depends on user's language
+environment.  The IM manages text inputing, and the OM manages text
+drawing.  Both IM and OM highly depend on LC data.
+</para>
+
+<para>
+In X11R5, there are two sample implementations, Ximp and Xsi, for
+Xlib internationalization.  But in both implementations, IM and OM
+actually refer the private extension of LC.  It breaks coexistence
+of these two sample implementations.  For example, if a user creates
+a new OM for special purpose as a part of Ximp, it will not work with
+Xsi.
+</para>
+
+<para>
+As a solution of this problem, we propose to define the standard
+APIs between these three objects, and define the structure that are
+common to these objects.

+A locale loader is an entry point for locale object, which

-The Double Buffer Extension (DBE) provides a standard way to utilize
-double-buffering within the framework of the X Window System.
-Double-buffering uses two buffers, called front and back, which hold images.
-The front buffer is visible to the user; the back buffer is not. Successive
-frames of an animation are rendered into the back buffer while the previously
-rendered frame is displayed in the front buffer. When a new frame is ready,
-the back and front buffers swap roles, making the new frame visible. Ideally,
-this exchange appears to happen instantaneously to the user and with no
-visual artifacts. Thus, only completely rendered images are presented to the
-user, and they remain visible during the entire time it takes to render a new
-frame. The result is a flicker-free animation.

-<title>Concepts</title>
-<para>
-Normal windows are created using the core CreateWindow request, which
-allocates a set of window attributes and, for InputOutput windows, a front
-buffer, into which an image can be drawn. The contents of this buffer will be
-displayed when the window is visible.
-</para>
-<para>
-This extension enables applications to use double-buffering with a window.
-This involves creating a second buffer, called a back buffer, and associating
-one or more back buffer names (XIDs) with the window for use when referring
-to (that is, drawing to or reading from) the window’s back buffer. The back
-buffer name is a DRAWABLE of type BACKBUFFER.
-</para>
-<para>
-DBE provides a relative double-buffering model. One XID, the window,
-always refers to the front buffer. One or more other XIDs, the back buffer
-names, always refer to the back buffer. After a buffer swap, the window
-continues to refer to the (new) front buffer, and the back buffer name
-continues to refer to the (new) back buffer. Thus, applications and toolkits
-that want to just render to the back buffer always use the back buffer name
-for all drawing requests to the window. Portions of an application that want
-to render to the front buffer always use the window XID for all drawing
-requests to the window.
-</para>
-<para>
-Multiple clients and toolkits can all use double-buffering on the same window.
-DBE does not provide a request for querying whether a window has
-double-buffering support, and if so, what the back buffer name is. Given the
-asynchronous nature of the X Window System, this would cause race
-conditions. Instead, DBE allows multiple back buffer names to exist for the
-same window; they all refer to the same physical back buffer. The first time a
-back buffer name is allocated for a window, the window becomes
-double-buffered and the back buffer name is associated with the window.
-Subsequently, the window already is a double-buffered window, and nothing
-about the window changes when a new back buffer name is allocated, except
-that the new back buffer name is associated with the window. The window
-remains double-buffered until either the window is destroyed or until all of the
-back buffer names for the window are deallocated.
-</para>
-<para>
-In general, both the front and back buffers are treated the same.
-particular, here are some important characteristics:
-</para>
-<itemizedlist>
-  <listitem>
-    <para>
-Only one buffer per window can be visible at a time (the front buffer).
-    </para>
-  </listitem>
-  <listitem>
-    <para>
-Both buffers associated with a window have the same visual type, depth,
-width, height, and shape as the window.
-    </para>
-  </listitem>
-  <listitem>
-    <para>
-Both buffers associated with a window are "visible" (or "obscured") in
-the same way. When an Expose event is generated for a window, both
-buffers should be considered to be damaged in the exposed area.
-Damage that occurs to either buffer will result in an Expose event on
-the window. When a double-buffered window is exposed, both buffers
-are tiled with the window background, exactly as stated by the core
-protocol. Even though the back buffer is not visible, terms such as
-obscure apply to the back buffer as well as to the front buffer.
-    </para>
-  </listitem>
-  <listitem>
-    <para>
-It is acceptable at any time to pass a BACKBUFFER in any request,
-notably any core or extension drawing request, that expects a
-DRAWABLE.  This enables an application to draw directly into
-BACKBUFFERs in the same fashion as it would draw into any other
-DRAWABLE.
-    </para>
-  </listitem>
-  <listitem>
-    <para>
-It is an error (Window) to pass a BACKBUFFER in a core request that

-If core X11 backing-store and save-under applies to a double-buffered
-window, it applies to both buffers equally.
-    </para>
-  </listitem>
-  <listitem>
-    <para>
-If the core ClearArea request is executed on a double-buffered window,
-the same area in both the front and back buffers is cleared.
-    </para>
-  </listitem>
-</itemizedlist>
-
-<para>
-The effect of passing a window to a request that accepts a
-<function>DRAWABLE</function> is
-unchanged by this extension. The window and front buffer are synonomous
-with each other. This includes obeying the <function>GetImage</function>
-semantics and the
-subwindow-mode semantics if a core graphics context is involved. Regardless
-of whether the window was explicitly passed in a
-<function>GetImage</function> request, or
-implicitly referenced (that is, one of the window’s ancestors was passed in the
-request), the front (that is, visible) buffer is always referenced. Thus,
-DBE-naive screen dump clients will always get the front buffer.
-<function>GetImage</function> on
-a back buffer returns undefined image contents for any obscured regions of the
-back buffer that fall within the image.
-</para>
-<para>
-Drawing to a back buffer always uses the clip region that would be used to
-draw to the front buffer with a GC subwindow-mode of
-<function>ClipByChildren</function>. If
-an ancestor of a double-buffered window is drawn to with a core GC having a
-subwindow-mode of IncludeInferiors, the effect on the double-buffered
-window’s back buffer depends on the depth of the double-buffered window
-and the ancestor. If the depths are the same, the contents of the back buffer
-of the double-buffered window are not changed. If the depths are different,
-the contents of the back buffer of the double-buffered window are undefined
-for the pixels that the <function>IncludeInferiors</function> drawing touched.
-</para>
-
-
-<para>
-DBE adds no new events. DBE does not extend the semantics of any existing
-events with the exception of adding a new DRAWABLE type called
-BACKBUFFER. If events, replies, or errors that contain a DRAWABLE (for
-example, <function>GraphicsExpose</function>) are generated in response to
-a request, the
-DRAWABLE returned will be the one specified in the request.
-</para>

-DBE advertises which visuals support double-buffering.
-</para>
-<para>
-DBE does not include any timing or synchronization facilities. Applications
-that need such facilities (for example, to maintain a constant frame rate)
-should investigate the Synchronization Extension, an X Consortium standard.
-</para>
-
-<sect1 id="window_management_operations">
-<title>Window Management Operations</title>
-
-<para>
-The basic philosophy of DBE is that both buffers are treated the same by core
-X window management operations.
-</para>
-<para>
-When the core <function>DestroyWindow</function> is executed on a
-double-buffered window, both buffers associated with the window are
-destroyed, and all back buffer names associated with the window are freed.
-</para>
-<para>
-If the core <function>ConfigureWindow</function> request changes the size
-of a window, both buffers assume the new size. If the window’s size
-increases, the effect on the buffers depends on whether the implementation
-honors bit gravity for buffers.
-If bit gravity is implemented, then the contents of both buffers are moved in
-accordance with the window’s bit gravity (see the core
-<function>ConfigureWindow</function>
-request), and the remaining areas are tiled with the window background. If
-bit gravity is not implemented, then the entire unobscured region of both
-buffers is tiled with the window background. In either case,
-<function>Expose</function> events are
-generated for the region that is tiled with the window background.
-If the core GetGeometry request is executed on a BACKBUFFER, the
-returned x, y, and border-width will be zero.
-</para>
-<para>
-If the Shape extension
-<function>ShapeRectangles</function>,
-<function>ShapeMask</function>,
-<function>ShapeCombine</function>, or
-<function>ShapeOffset</function>
-request is executed on a double-buffered window, both buffers
-are reshaped to match the new window shape. The region difference is the
-following:
-</para>
-
-<literallayout remap='Ds'>
-        D = newshape − oldshape
-</literallayout>
-
-<para>
-It is tiled with the window background in both buffers, and
-<function>Expose</function>
-events are generated for D.

-<sect1 id="complex_swap_actions">
-<title>Complex Swap Actions</title>
-<para>
-DBE has no explicit knowledge of ancillary buffers (for example, depth buffers
-or alpha buffers), and only has a limited set of defined swap actions. Some
-applications may need a richer set of swap actions than DBE provides. Some
-DBE implementations have knowledge of ancillary buffers, and/or can provide
-a rich set of swap actions. Instead of continually extending DBE to increase
-its set of swap actions, DBE provides a flexible "idiom" mechanism. If an
-application’s needs are served by the defined swap actions, it should use them;
-otherwise, it should use the following method of expressing a complex swap
-action as an idiom. Following this policy will ensure the best possible
-performance across a wide variety of implementations.
-</para>
-<para>
-As suggested by the term "idiom," a complex swap action should be expressed
-as a group/series of requests. Taken together, this group of requests may be
-combined into an atomic operation by the implementation, in order to
-maximize performance. The set of idioms actually recognized for optimization
-is implementation dependent.
-To help with idiom expression and
-interpretation, an idiom must be surrounded by two protocol requests:
-<function>DBEBeginIdiom</function> and <function>DBEEndIdiom</function>.
-Unless this begin-end pair surrounds the idiom, it may not be recognized
-by a given implementation, and performance will suffer.
-</para>
-<para>
-For example, if an application wants to swap buffers for two windows, and use
-core X to clear only certain planes of the back buffers, the application would
-issue the following protocol requests as a group, and in the following order:
-</para>
-

-    </para>
-  </listitem>
-  <listitem>
-    <para>
-<function>DBESwapBuffers</function> request with XIDs for two windows, each of which uses
-a swap action of Untouched.

-  </listitem>
-</itemizedlist>
-
-<para>
-The <function>DBEBeginIdiom</function> and <function>DBEEndIdiom</function>
-requests do not perform any actions
-themselves. They are treated as markers by implementations that can
-combine certain groups/series of requests as idioms, and are ignored by other
-implementations or for nonrecognized groups/series of requests. If these
-requests are sent out of order, or are mismatched, no errors are sent, and the
-requests are executed as usual, though performance may suffer.
-</para>
-
-<para>
-
-An idiom need not include a <function>DBESwapBuffers</function> request.
-For example, if a swap action of <function>Copied</function> is desired,
-but only some of the planes should be copied, a core X
-<function>CopyArea</function> request may be used instead of
-<function>DBESwapBuffers</function>. If
-<function>DBESwapBuffers</function> is included in an idiom, it should
-immediately follow the
-<function>DBEBeginIdiom</function> request. Also, when the
-<function>DBESwapBuffers</function> is included in an idiom, that
-request’s swap action will still be valid, and if the swap action
-might overlap with another request, then the final result of the idiom must be
-as if the separate requests were executed serially. For example, if the
-specified swap action is <function>Untouched</function>, and if a
-<function>PolyFillRectangle</function> using a client clip
-rectangle is done to the window’s back buffer after the
-<function>DBESwapBuffers</function> request, then the contents of the new
-back buffer (after the idiom) will be the
-same as if the idiom was not recognized by the implementation.
-</para>
-<para>
-It is highly recommended that Application Programming Interface (API)
-providers define, and application developers use, "convenience" functions that
-allow client applications to call one procedure that encapsulates common
-idioms. These functions will generate the
-<function>DBEBeginIdiom</function> request, the idiom
-requests, and <function>DBEEndIdiom</function> request. Usage of these
-functions will ensure best possible performance across a wide
-variety of implementations.

+The Double Buffer Extension (DBE) provides a standard way to utilize
+double-buffering within the framework of the X Window System.
+Double-buffering uses two buffers, called front and back, which hold images.
+The front buffer is visible to the user; the back buffer is not. Successive
+frames of an animation are rendered into the back buffer while the previously
+rendered frame is displayed in the front buffer. When a new frame is ready,
+the back and front buffers swap roles, making the new frame visible. Ideally,
+this exchange appears to happen instantaneously to the user and with no
+visual artifacts. Thus, only completely rendered images are presented to the
+user, and they remain visible during the entire time it takes to render a new
+frame. The result is a flicker-free animation.

+<para>
+Normal windows are created using the core CreateWindow request, which
+allocates a set of window attributes and, for InputOutput windows, a front
+buffer, into which an image can be drawn. The contents of this buffer will be
+displayed when the window is visible.
+</para>
+<para>
+This extension enables applications to use double-buffering with a window.
+This involves creating a second buffer, called a back buffer, and associating
+one or more back buffer names (XIDs) with the window for use when referring
+to (that is, drawing to or reading from) the window’s back buffer. The back
+buffer name is a DRAWABLE of type BACKBUFFER.
+</para>
+<para>
+DBE provides a relative double-buffering model. One XID, the window,
+always refers to the front buffer. One or more other XIDs, the back buffer
+names, always refer to the back buffer. After a buffer swap, the window
+continues to refer to the (new) front buffer, and the back buffer name
+continues to refer to the (new) back buffer. Thus, applications and toolkits
+that want to just render to the back buffer always use the back buffer name
+for all drawing requests to the window. Portions of an application that want
+to render to the front buffer always use the window XID for all drawing
+requests to the window.
+</para>
+<para>
+Multiple clients and toolkits can all use double-buffering on the same window.
+DBE does not provide a request for querying whether a window has
+double-buffering support, and if so, what the back buffer name is. Given the
+asynchronous nature of the X Window System, this would cause race
+conditions. Instead, DBE allows multiple back buffer names to exist for the
+same window; they all refer to the same physical back buffer. The first time a
+back buffer name is allocated for a window, the window becomes
+double-buffered and the back buffer name is associated with the window.
+Subsequently, the window already is a double-buffered window, and nothing
+about the window changes when a new back buffer name is allocated, except
+that the new back buffer name is associated with the window. The window
+remains double-buffered until either the window is destroyed or until all of the
+back buffer names for the window are deallocated.
+</para>
+<para>
+In general, both the front and back buffers are treated the same.
+particular, here are some important characteristics:
+</para>
+<itemizedlist>
+  <listitem>
+    <para>
+Only one buffer per window can be visible at a time (the front buffer).
+    </para>
+  </listitem>
+  <listitem>
+    <para>
+Both buffers associated with a window have the same visual type, depth,
+width, height, and shape as the window.
+    </para>
+  </listitem>
+  <listitem>
+    <para>
+Both buffers associated with a window are "visible" (or "obscured") in
+the same way. When an Expose event is generated for a window, both
+buffers should be considered to be damaged in the exposed area.
+Damage that occurs to either buffer will result in an Expose event on
+the window. When a double-buffered window is exposed, both buffers
+are tiled with the window background, exactly as stated by the core
+protocol. Even though the back buffer is not visible, terms such as
+obscure apply to the back buffer as well as to the front buffer.
+    </para>
+  </listitem>
+  <listitem>
+    <para>
+It is acceptable at any time to pass a BACKBUFFER in any request,
+notably any core or extension drawing request, that expects a
+DRAWABLE.  This enables an application to draw directly into
+BACKBUFFERs in the same fashion as it would draw into any other
+DRAWABLE.
+    </para>
+  </listitem>
+  <listitem>
+    <para>
+It is an error (Window) to pass a BACKBUFFER in a core request that
+expects a Window.
+    </para>
+  </listitem>
+  <listitem>
+    <para>
+A BACKBUFFER will never be sent by core X in a reply, event, or
+error where a Window is specified.
+    </para>
+  </listitem>
+  <listitem>
+    <para>
+If core X11 backing-store and save-under applies to a double-buffered
+window, it applies to both buffers equally.
+    </para>
+  </listitem>
+  <listitem>
+    <para>
+If the core ClearArea request is executed on a double-buffered window,
+the same area in both the front and back buffers is cleared.
+    </para>
+  </listitem>
+</itemizedlist>
+
+<para>
+The effect of passing a window to a request that accepts a
+<function>DRAWABLE</function> is
+unchanged by this extension. The window and front buffer are synonomous
+with each other. This includes obeying the <function>GetImage</function>
+semantics and the
+subwindow-mode semantics if a core graphics context is involved. Regardless
+of whether the window was explicitly passed in a
+<function>GetImage</function> request, or
+implicitly referenced (that is, one of the window’s ancestors was passed in the
+request), the front (that is, visible) buffer is always referenced. Thus,
+DBE-naive screen dump clients will always get the front buffer.
+<function>GetImage</function> on
+a back buffer returns undefined image contents for any obscured regions of the
+back buffer that fall within the image.
+</para>
+<para>
+Drawing to a back buffer always uses the clip region that would be used to
+draw to the front buffer with a GC subwindow-mode of
+<function>ClipByChildren</function>. If
+an ancestor of a double-buffered window is drawn to with a core GC having a
+subwindow-mode of IncludeInferiors, the effect on the double-buffered
+window’s back buffer depends on the depth of the double-buffered window
+and the ancestor. If the depths are the same, the contents of the back buffer
+of the double-buffered window are not changed. If the depths are different,
+the contents of the back buffer of the double-buffered window are undefined
+for the pixels that the <function>IncludeInferiors</function> drawing touched.
+</para>
+
+
+<para>
+DBE adds no new events. DBE does not extend the semantics of any existing
+events with the exception of adding a new DRAWABLE type called
+BACKBUFFER. If events, replies, or errors that contain a DRAWABLE (for
+example, <function>GraphicsExpose</function>) are generated in response to
+a request, the
+DRAWABLE returned will be the one specified in the request.
+</para>

+DBE advertises which visuals support double-buffering.

+DBE does not include any timing or synchronization facilities. Applications
+that need such facilities (for example, to maintain a constant frame rate)
+should investigate the Synchronization Extension, an X Consortium standard.
+</para>
+
+<sect1 id="window_management_operations">
+<title>Window Management Operations</title>
+
+<para>
+The basic philosophy of DBE is that both buffers are treated the same by core
+X window management operations.
+</para>
+<para>
+When the core <function>DestroyWindow</function> is executed on a
+double-buffered window, both buffers associated with the window are
+destroyed, and all back buffer names associated with the window are freed.
+</para>
+<para>
+If the core <function>ConfigureWindow</function> request changes the size
+of a window, both buffers assume the new size. If the window’s size
+increases, the effect on the buffers depends on whether the implementation
+honors bit gravity for buffers.
+If bit gravity is implemented, then the contents of both buffers are moved in
+accordance with the window’s bit gravity (see the core
+<function>ConfigureWindow</function>
+request), and the remaining areas are tiled with the window background. If
+bit gravity is not implemented, then the entire unobscured region of both
+buffers is tiled with the window background. In either case,
+<function>Expose</function> events are
+generated for the region that is tiled with the window background.
+If the core GetGeometry request is executed on a BACKBUFFER, the
+returned x, y, and border-width will be zero.
+</para>
+<para>
+If the Shape extension
+<function>ShapeRectangles</function>,
+<function>ShapeMask</function>,
+<function>ShapeCombine</function>, or
+<function>ShapeOffset</function>
+request is executed on a double-buffered window, both buffers
+are reshaped to match the new window shape. The region difference is the
+following:

+
+<literallayout remap='Ds'>
+        D = newshape − oldshape

+<function>Expose</function>
+events are generated for D.

+
+<sect1 id="complex_swap_actions">
+<title>Complex Swap Actions</title>
+<para>
+DBE has no explicit knowledge of ancillary buffers (for example, depth buffers
+or alpha buffers), and only has a limited set of defined swap actions. Some
+applications may need a richer set of swap actions than DBE provides. Some
+DBE implementations have knowledge of ancillary buffers, and/or can provide
+a rich set of swap actions. Instead of continually extending DBE to increase
+its set of swap actions, DBE provides a flexible "idiom" mechanism. If an
+application’s needs are served by the defined swap actions, it should use them;
+otherwise, it should use the following method of expressing a complex swap
+action as an idiom. Following this policy will ensure the best possible
+performance across a wide variety of implementations.
+</para>
+<para>
+As suggested by the term "idiom," a complex swap action should be expressed
+as a group/series of requests. Taken together, this group of requests may be
+combined into an atomic operation by the implementation, in order to
+maximize performance. The set of idioms actually recognized for optimization
+is implementation dependent.
+To help with idiom expression and
+interpretation, an idiom must be surrounded by two protocol requests:
+<function>DBEBeginIdiom</function> and <function>DBEEndIdiom</function>.
+Unless this begin-end pair surrounds the idiom, it may not be recognized
+by a given implementation, and performance will suffer.
+</para>
+<para>
+For example, if an application wants to swap buffers for two windows, and use
+core X to clear only certain planes of the back buffers, the application would
+issue the following protocol requests as a group, and in the following order:
+</para>
+
+<itemizedlist>
+  <listitem>
+    <para>
+<function>DBEBeginIdiom</function> request.
+    </para>
+  </listitem>
+  <listitem>
+    <para>
+<function>DBESwapBuffers</function> request with XIDs for two windows, each of which uses
+a swap action of Untouched.
+    </para>
+  </listitem>
+  <listitem>
+    <para>
+Core X <function>PolyFillRectangle</function> request to the back buffer of one window.
+    </para>

+    <para>
+<function>DBEEndIdiom</function> request.
+    </para>
+  </listitem>
+</itemizedlist>
+
+<para>
+The <function>DBEBeginIdiom</function> and <function>DBEEndIdiom</function>
+requests do not perform any actions
+themselves. They are treated as markers by implementations that can
+combine certain groups/series of requests as idioms, and are ignored by other
+implementations or for nonrecognized groups/series of requests. If these
+requests are sent out of order, or are mismatched, no errors are sent, and the
+requests are executed as usual, though performance may suffer.
+</para>
+
+<para>
+
+An idiom need not include a <function>DBESwapBuffers</function> request.
+For example, if a swap action of <function>Copied</function> is desired,
+but only some of the planes should be copied, a core X
+<function>CopyArea</function> request may be used instead of
+<function>DBESwapBuffers</function>. If
+<function>DBESwapBuffers</function> is included in an idiom, it should
+immediately follow the
+<function>DBEBeginIdiom</function> request. Also, when the
+<function>DBESwapBuffers</function> is included in an idiom, that
+request’s swap action will still be valid, and if the swap action
+might overlap with another request, then the final result of the idiom must be
+as if the separate requests were executed serially. For example, if the
+specified swap action is <function>Untouched</function>, and if a
+<function>PolyFillRectangle</function> using a client clip
+rectangle is done to the window’s back buffer after the
+<function>DBESwapBuffers</function> request, then the contents of the new
+back buffer (after the idiom) will be the
+same as if the idiom was not recognized by the implementation.
+</para>
+<para>
+It is highly recommended that Application Programming Interface (API)
+providers define, and application developers use, "convenience" functions that
+allow client applications to call one procedure that encapsulates common
+idioms. These functions will generate the
+<function>DBEBeginIdiom</function> request, the idiom
+requests, and <function>DBEEndIdiom</function> request. Usage of these
+functions will ensure best possible performance across a wide
+variety of implementations.

-<title>Overview</title>
-
-<para>This extension provides X Protocol control over the VESA Display
-Power Management Signaling (DPMS) characteristics of video boards
-under control of the X Window System.
-</para>
-
-<para>
-Traditionally, the X Window System has provided for both blanking and
-non-blanking screen savers.  Timeouts associated with these built-in
-screen saver mechanisms are limited to idle (dwell) time, and a change
-timeout that specifies the change interval for non-blanking screen savers.
-</para>
-
-<para>
-The United States' Environmental Protection Agency (EPA) Energy Star program
-requires that monitors power down after some idle time by default.
-While it is possible to simply overload the existing screen saver timeouts,
-this solution leaves the non-privileged user little to no control over
-the DPMS characteristics of his or her system.  For example, disabling
-DPMS would require some unintended side effect in the core screen saver,
-such as disabling the changing of a non-blanking screen saver.  Providing
-clients with this control requires an extension to the core X Window System
-Protocol, and this extension seeks to fill this gap.
-</para>
-
-<para>
-There are four power levels specified by the Video Electronics Standards
-Association (VESA) Display Power Management Signaling (DPMS) standard.
-These are mapped onto the X DPMS Extension like this:

-<para>
-The value <emphasis remap='I'>standby</emphasis> is the amount of time of
-inactivity in seconds before standby mode is invoked. The actual effects of
-this mode are implementation defined, but in the case of DPMS compliant
-hardware, it is implemented by shutting off the horizontal sync signal,
-and pulsing the vertical sync signal.
-Standby mode provides the quickest monitor recovery time.  Note also that
-many monitors implement this mode identically to suspend mode.  A value
-of zero disables this mode.
-</para>
-
-<para>
-The value <emphasis remap='I'>suspend</emphasis> is the amount of time of
-inactivity in seconds before the second level of power savings is invoked.
-Suspend mode's physical and electrical characteristics are implementation
-defined, but in DPMS compliant hardware, results in the pulsing of the
-horizontal sync signal, and shutting off of the vertical sync signal.
-Suspend mode recovery is considered to be slower than standby mode, but
-faster than off mode, however this is monitor dependent.  As noted above,
-many monitors implement this mode identically to standby mode.  A value of
-zero disables this mode.
-</para>
-
-<para>
-The value <emphasis remap='I'>off</emphasis> is the amount of time of
-inactivity in seconds before the third and final level of power savings is
-invoked. Off mode's physical and electrical characteristics are
-implementation defined, but in DPMS compliant hardware, is implemented by
-shutting off both horizontal and vertical sync signals, resulting in
-the power-down of the monitor.  Recovery time is implementation dependant,
-but frequently is similar to the power-up time of the monitor.  A value
-of zero disables this mode.
-</para>
-
-<para>
-Chronologically, standby mode occurs before or simultaneously with
-suspend mode, and suspend mode must occur before or simultaneously with
-off mode.  Therefore, non-zero mode timeout values must be greater than
-or equal to the timeout values of earlier modes.  If inconsistent values
-are supplied, a BadValue error will result.

+<title>Overview</title>
+
+<para>This extension provides X Protocol control over the VESA Display
+Power Management Signaling (DPMS) characteristics of video boards
+under control of the X Window System.
+</para>
+
+<para>
+Traditionally, the X Window System has provided for both blanking and
+non-blanking screen savers.  Timeouts associated with these built-in
+screen saver mechanisms are limited to idle (dwell) time, and a change
+timeout that specifies the change interval for non-blanking screen savers.
+</para>
+
+<para>
+The United States' Environmental Protection Agency (EPA) Energy Star program
+requires that monitors power down after some idle time by default.
+While it is possible to simply overload the existing screen saver timeouts,
+this solution leaves the non-privileged user little to no control over
+the DPMS characteristics of his or her system.  For example, disabling
+DPMS would require some unintended side effect in the core screen saver,
+such as disabling the changing of a non-blanking screen saver.  Providing
+clients with this control requires an extension to the core X Window System
+Protocol, and this extension seeks to fill this gap.
+</para>
+
+<para>
+There are four power levels specified by the Video Electronics Standards
+Association (VESA) Display Power Management Signaling (DPMS) standard.
+These are mapped onto the X DPMS Extension like this:

+The DPMSSetTimeouts function permits applications to set the timeout values

+</para>
+
+<para>
+The value <emphasis remap='I'>standby</emphasis> is the amount of time of
+inactivity in seconds before standby mode is invoked. The actual effects of
+this mode are implementation defined, but in the case of DPMS compliant
+hardware, it is implemented by shutting off the horizontal sync signal,
+and pulsing the vertical sync signal.
+Standby mode provides the quickest monitor recovery time.  Note also that
+many monitors implement this mode identically to suspend mode.  A value
+of zero disables this mode.
+</para>
+
+<para>
+The value <emphasis remap='I'>suspend</emphasis> is the amount of time of
+inactivity in seconds before the second level of power savings is invoked.
+Suspend mode's physical and electrical characteristics are implementation
+defined, but in DPMS compliant hardware, results in the pulsing of the
+horizontal sync signal, and shutting off of the vertical sync signal.
+Suspend mode recovery is considered to be slower than standby mode, but
+faster than off mode, however this is monitor dependent.  As noted above,
+many monitors implement this mode identically to standby mode.  A value of
+zero disables this mode.
+</para>
+
+<para>
+The value <emphasis remap='I'>off</emphasis> is the amount of time of
+inactivity in seconds before the third and final level of power savings is
+invoked. Off mode's physical and electrical characteristics are
+implementation defined, but in DPMS compliant hardware, is implemented by
+shutting off both horizontal and vertical sync signals, resulting in
+the power-down of the monitor.  Recovery time is implementation dependant,
+but frequently is similar to the power-up time of the monitor.  A value
+of zero disables this mode.
+</para>
+
+<para>
+Chronologically, standby mode occurs before or simultaneously with
+suspend mode, and suspend mode must occur before or simultaneously with
+off mode.  Therefore, non-zero mode timeout values must be greater than
+or equal to the timeout values of earlier modes.  If inconsistent values
+are supplied, a BadValue error will result.

-<title>Overview</title>
-
-<para>This extension provides arbitrary window and border shapes within
-the X11 protocol.
-</para>
-
-<para>
-The restriction of rectangular windows within the X protocol is a significant
-limitation in the implementation of many styles of user interface.  For
-example, many transient windows would like to display a
-&ldquo;drop shadow&rdquo; to give the illusion of 3 dimensions.  As
-another example, some user interface style guides call for buttons with
-rounded corners; the full simulation of a nonrectangular shape,
-particularly with respect to event distribution and cursor shape, is not
-possible within the core X protocol.  As a final example, round clocks
-and nonrectangular icons are desirable visual addition to the desktop.
-</para>
-
-<para>
-This extension provides mechanisms for changing the visible shape of a
-window to an arbitrary, possibly disjoint, nonrectangular form.  The intent
-of the extension is to supplement the existing semantics, not replace them.
-In particular, it is desirable for clients that are unaware of the
-extension to still be able to cope reasonably with shaped windows.  For
-example, window managers should still be able to negotiate screen
-real estate in rectangular pieces.  Toward this end, any shape specified for
-a window is clipped by the bounding rectangle for the window as specified by
-the window's geometry in the core protocol.  An expected convention would be
-that client programs expand their shape to fill the area offered by the
-window manager.
-</para>
-</chapter>
-
-<chapter id='description'>
-<title>Description</title>
-
-<para>
-Each window (even with no shapes specified) is defined by two regions:  the
-<emphasis remap='I'>bounding region</emphasis> and the
-<emphasis remap='I'>clip region</emphasis>.  The bounding region is the
-area of the parent window that the window will occupy (including border).
-The clip region is the subset of the bounding region that is available for
-subwindows and graphics.  The area between the bounding region and the
-clip region is defined to be the border of the window.
-</para>
-
-<para>
-A nonshaped window will have a bounding region that is a rectangle spanning
-the window, including its border; the clip region will be a rectangle
-filling the inside dimensions (not including the border).  In this document,
-these areas are referred to as the
-<emphasis remap='I'>default bounding region</emphasis> and the
-<emphasis remap='I'>default clip region</emphasis>.  For a window with
-inside size of <emphasis remap='I'>width</emphasis> by
-<emphasis remap='I'>height</emphasis> and border width
-<emphasis remap='I'>bwidth</emphasis>, the default bounding and clip
-regions are the rectangles (relative to the window origin):

-<para>
-This extension allows a client to modify either or both of the bounding or
-clip regions by specifying new regions that combine with the default
-regions.  These new regions are called the
-<emphasis remap='I'>client bounding region</emphasis> and the
-<emphasis remap='I'>client clip region</emphasis>.  They are specified
-relative to the origin of the window and are always defined by offsets
-relative to the window origin (that is, region adjustments are not
-required when the window is moved).  Three mechanisms for specifying
-regions are provided:  a list of rectangles, a bitmap, and an existing
-bounding or clip region from a window.  This is modeled on the specification
-of regions in graphics contexts in the core protocol and allows a variety
-of different uses of the extension.
-</para>
-
-<para>
-When using an existing window shape as an operand in specifying a new shape,
-the client region is used, unless none has been set, in which case the
-default region is used instead.
-</para>
-
-<para>
-The <emphasis remap='I'>effective bounding region</emphasis> of a window is
-defined to be the intersection of the client bounding region with the default
-bounding region.  Any portion of the client bounding region that is not
-included in the default bounding region will not be included in the
-effective bounding region on the screen.  This means that window managers
-(or other geometry managers) used to dealing with rectangular client windows
-will be able to constrain the client to a rectangular area of the screen.
-</para>
-
-<para>
-Construction of the effective bounding region is dynamic; the client bounding
-region is not mutated to obtain the effective bounding region.  If a client
-bounding region is specified that extends beyond the current default bounding
-region, and the window is later enlarged, the effective bounding region will
-be enlarged to include more of the client bounding region.
-</para>
-
-<para>
-The <emphasis remap='I'>effective clip region</emphasis> of a window is
-defined to be the intersection of the client clip region with both the
-default clip region and the client bounding region.  Any portion of the
-client clip region that is not included in both the default clip region
-and the client bounding region will not be included in the effective clip
-region on the screen.
-</para>
-
-<para>
-Construction of the effective clip region is dynamic; the client clip region is
-not mutated to obtain the effective clip region.  If a client clip region is
-specified that extends beyond the current default clip region and the
-window or its bounding region is later enlarged, the effective clip region will
-be enlarged to include more of the client clip region if it is included in
-the effective bounding region.
-</para>
-
-<para>
-The border of a window is defined to be the difference between the effective
-bounding region and the effective clip region.  If this region is empty, no
-border is displayed.  If this region is nonempty, the border is filled
-using the border-tile or border-pixel of the window as specified in the core
-protocol.  Note that a window with a nonzero border width will never be able
-to draw beyond the default clip region of the window.  Also note that a zero
-border width does not prevent a window from having a border, since the clip
-shape can still be made smaller than the bounding shape.
-</para>
-
-<para>
-All output to the window and visible regions of any subwindows will be
-clipped to the effective clip region.  The server must not retain window
-contents beyond the effective bounding region with backing store.  The window's
-origin (for graphics operations, background tiling, and subwindow placement)
-is not affected by the existence of a bounding region or clip region.
-</para>
-
-<para>
-Areas that are inside the default bounding region but outside the effective
-bounding region are not part of the window; these areas of the screen will
-be occupied by other windows.  Input events that occur within the default
-bounding region but outside the effective bounding region will be delivered as
-if the window was not occluding the event position.  Events that occur in
-a nonrectangular border of a window will be delivered to that window, just
-as for events that occur in a normal rectangular border.

+<title>Overview</title>
+
+<para>This extension provides arbitrary window and border shapes within
+the X11 protocol.
+</para>
+
+<para>
+The restriction of rectangular windows within the X protocol is a significant
+limitation in the implementation of many styles of user interface.  For
+example, many transient windows would like to display a
+&ldquo;drop shadow&rdquo; to give the illusion of 3 dimensions.  As
+another example, some user interface style guides call for buttons with
+rounded corners; the full simulation of a nonrectangular shape,
+particularly with respect to event distribution and cursor shape, is not
+possible within the core X protocol.  As a final example, round clocks
+and nonrectangular icons are desirable visual addition to the desktop.
+</para>
+
+<para>
+This extension provides mechanisms for changing the visible shape of a
+window to an arbitrary, possibly disjoint, nonrectangular form.  The intent
+of the extension is to supplement the existing semantics, not replace them.
+In particular, it is desirable for clients that are unaware of the
+extension to still be able to cope reasonably with shaped windows.  For
+example, window managers should still be able to negotiate screen
+real estate in rectangular pieces.  Toward this end, any shape specified for
+a window is clipped by the bounding rectangle for the window as specified by
+the window's geometry in the core protocol.  An expected convention would be
+that client programs expand their shape to fill the area offered by the
+window manager.
+</para>

+
+<chapter id='description'>
+<title>Description</title>
+
+<para>
+Each window (even with no shapes specified) is defined by two regions:  the
+<emphasis remap='I'>bounding region</emphasis> and the
+<emphasis remap='I'>clip region</emphasis>.  The bounding region is the
+area of the parent window that the window will occupy (including border).
+The clip region is the subset of the bounding region that is available for
+subwindows and graphics.  The area between the bounding region and the
+clip region is defined to be the border of the window.
+</para>
+
+<para>
+A nonshaped window will have a bounding region that is a rectangle spanning
+the window, including its border; the clip region will be a rectangle
+filling the inside dimensions (not including the border).  In this document,
+these areas are referred to as the
+<emphasis remap='I'>default bounding region</emphasis> and the
+<emphasis remap='I'>default clip region</emphasis>.  For a window with
+inside size of <emphasis remap='I'>width</emphasis> by
+<emphasis remap='I'>height</emphasis> and border width
+<emphasis remap='I'>bwidth</emphasis>, the default bounding and clip
+regions are the rectangles (relative to the window origin):

+</literallayout>
+
+<para>
+This extension allows a client to modify either or both of the bounding or
+clip regions by specifying new regions that combine with the default
+regions.  These new regions are called the
+<emphasis remap='I'>client bounding region</emphasis> and the
+<emphasis remap='I'>client clip region</emphasis>.  They are specified
+relative to the origin of the window and are always defined by offsets
+relative to the window origin (that is, region adjustments are not
+required when the window is moved).  Three mechanisms for specifying
+regions are provided:  a list of rectangles, a bitmap, and an existing
+bounding or clip region from a window.  This is modeled on the specification
+of regions in graphics contexts in the core protocol and allows a variety
+of different uses of the extension.
+</para>
+
+<para>
+When using an existing window shape as an operand in specifying a new shape,

+</para>
+
+<para>
+The <emphasis remap='I'>effective bounding region</emphasis> of a window is
+defined to be the intersection of the client bounding region with the default
+bounding region.  Any portion of the client bounding region that is not
+included in the default bounding region will not be included in the
+effective bounding region on the screen.  This means that window managers
+(or other geometry managers) used to dealing with rectangular client windows
+will be able to constrain the client to a rectangular area of the screen.
+</para>
+
+<para>
+Construction of the effective bounding region is dynamic; the client bounding
+region is not mutated to obtain the effective bounding region.  If a client
+bounding region is specified that extends beyond the current default bounding
+region, and the window is later enlarged, the effective bounding region will
+be enlarged to include more of the client bounding region.

+
+<para>
+The <emphasis remap='I'>effective clip region</emphasis> of a window is

+Construction of the effective clip region is dynamic; the client clip region is

+

+The border of a window is defined to be the difference between the effective
+bounding region and the effective clip region.  If this region is empty, no
+border is displayed.  If this region is nonempty, the border is filled
+using the border-tile or border-pixel of the window as specified in the core
+protocol.  Note that a window with a nonzero border width will never be able
+to draw beyond the default clip region of the window.  Also note that a zero
+border width does not prevent a window from having a border, since the clip
+shape can still be made smaller than the bounding shape.
+</para>
+
+<para>
+All output to the window and visible regions of any subwindows will be
+clipped to the effective clip region.  The server must not retain window
+contents beyond the effective bounding region with backing store.  The window's
+origin (for graphics operations, background tiling, and subwindow placement)
+is not affected by the existence of a bounding region or clip region.
+</para>
+
+<para>
+Areas that are inside the default bounding region but outside the effective
+bounding region are not part of the window; these areas of the screen will
+be occupied by other windows.  Input events that occur within the default
+bounding region but outside the effective bounding region will be delivered as
+if the window was not occluding the event position.  Events that occur in
+a nonrectangular border of a window will be delivered to that window, just
+as for events that occur in a normal rectangular border.

+<para>An
+<function>InputOnly</function>

+in this extension.
+</para>
+
+<para>
+The server must accept changes to the clip region of a root window, but

-<chapter id="synchronization_protocol">
-<title>Synchronization Protocol</title>
-
-<para>
-The core X protocol makes no guarantees about the relative order of
-execution of requests for different clients.  This means that any
-synchronization between clients must be done at the client level in an
-operating system-dependent and network-dependent manner. Even if there
-was an accepted standard for such synchronization, the use of a network
-introduces unpredictable delays between the synchronization of the clients and
-the delivery of the resulting requests to the X server.
-</para>
-<para>
-The core X protocol also makes no guarantees about the time at which
-requests are executed, which means that all clients with real-time constraints
-must implement their timing on the host computer. Any such timings are
-subject to error introduced by delays within the operating system and
-network and are ineﬃcient because of the need for round-trip requests that
-keep the client and server synchronized.
-</para>
-<para>
-The synchronization extension provides primitives that allow synchronization
-between clients to take place entirely within the X server. This removes any
-error introduced by the network and makes it possible to synchronize clients
-on different hosts running different operating systems. This is important for
-multimedia applications, where audio, video, and graphics data streams are
-being synchronized. The extension also provides internal timers within the X
-server to which client requests can be synchronized. This allows simple
-animation applications to be implemented without any round-trip requests
-and makes best use of buffering within the client, network, and server.
-</para>
-
-<sect1 id="description">
-<title>Description</title>
-<para>
-The mechanism used by this extension for synchronization within the X server
-is to block the processing of requests from a client until a specific
-synchronization condition occurs. When the condition occurs, the client is
-released and processing of requests continues. Multiple clients may block on
-the same condition to give inter-client synchronization. Alternatively, a single
-client may block on a condition such as an animation frame marker.
-</para>
-<para>
-The extension adds <function>Counter</function> and
-<function>Alarm</function> to the set of resources managed by
-the server. A counter has a 64-bit integer value that may be increased or
-decreased by client requests or by the server internally. A client can
-block by sending an <function>Await</function> request that waits until
-one of a set of synchronization conditions, called TRIGGERs, becomes TRUE.
-</para>
-<para>
-The <function>CreateCounter</function> request allows a client to create
-a <function>Counter</function> that can be changed by explicit
-<function>SetCounter</function> and <function>ChangeCounter</function>
-requests. These can be used to implement synchronization between
-different clients.
-</para>
-<para>
-There are some counters, called <function>System Counters</function>,
-that are changed by the server internally rather than by client
-requests. The effect of any change to a system counter is not visible
-until the server has finished processing the current request. In other
-words, system counters are apparently updated in the gaps between the
-execution of requests rather than during the actual execution of a
-request. The extension provides a system counter that advances with the
-server time as defined by the core protocol, and it may also provide
-counters that advance with the real-world time or that change each
-time the CRT screen is refreshed. Other extensions may provide their own
-extension-specific system counters.
-</para>
-<para>
-The extension provides an <function>Alarm</function> mechanism that allows clients to receive an
-event on a regular basis when a particular counter is changed.

+<title>Synchronization Protocol</title>
+
+<para>
+The core X protocol makes no guarantees about the relative order of
+execution of requests for different clients.  This means that any
+synchronization between clients must be done at the client level in an
+operating system-dependent and network-dependent manner. Even if there
+was an accepted standard for such synchronization, the use of a network
+introduces unpredictable delays between the synchronization of the clients and
+the delivery of the resulting requests to the X server.
+</para>
+<para>
+The core X protocol also makes no guarantees about the time at which
+requests are executed, which means that all clients with real-time constraints
+must implement their timing on the host computer. Any such timings are
+subject to error introduced by delays within the operating system and
+network and are ineﬃcient because of the need for round-trip requests that
+keep the client and server synchronized.
+</para>
+<para>
+The synchronization extension provides primitives that allow synchronization
+between clients to take place entirely within the X server. This removes any
+error introduced by the network and makes it possible to synchronize clients
+on different hosts running different operating systems. This is important for
+multimedia applications, where audio, video, and graphics data streams are
+being synchronized. The extension also provides internal timers within the X
+server to which client requests can be synchronized. This allows simple
+animation applications to be implemented without any round-trip requests
+and makes best use of buffering within the client, network, and server.
+</para>
+
+<sect1 id="description">
+<title>Description</title>
+<para>
+The mechanism used by this extension for synchronization within the X server
+is to block the processing of requests from a client until a specific
+synchronization condition occurs. When the condition occurs, the client is
+released and processing of requests continues. Multiple clients may block on
+the same condition to give inter-client synchronization. Alternatively, a single
+client may block on a condition such as an animation frame marker.
+</para>
+<para>
+The extension adds <function>Counter</function> and
+<function>Alarm</function> to the set of resources managed by
+the server. A counter has a 64-bit integer value that may be increased or
+decreased by client requests or by the server internally. A client can
+block by sending an <function>Await</function> request that waits until
+one of a set of synchronization conditions, called TRIGGERs, becomes TRUE.
+</para>
+<para>
+The <function>CreateCounter</function> request allows a client to create
+a <function>Counter</function> that can be changed by explicit
+<function>SetCounter</function> and <function>ChangeCounter</function>
+requests. These can be used to implement synchronization between
+different clients.
+</para>
+<para>
+There are some counters, called <function>System Counters</function>,
+that are changed by the server internally rather than by client
+requests. The effect of any change to a system counter is not visible
+until the server has finished processing the current request. In other
+words, system counters are apparently updated in the gaps between the
+execution of requests rather than during the actual execution of a
+request. The extension provides a system counter that advances with the
+server time as defined by the core protocol, and it may also provide
+counters that advance with the real-world time or that change each
+time the CRT screen is refreshed. Other extensions may provide their own
+extension-specific system counters.
+</para>
+<para>
+The extension provides an <function>Alarm</function> mechanism that allows clients to receive an
+event on a regular basis when a particular counter is changed.
