-1. Overview
-
-    The client-to-server DMX extension to the X protocol (DMX) provides
-    normal client applications with the ability to determine information
-    about the characteristics of the Xdmx server and the back-end X
-    servers that DMX is using.
-
-    The name for this extension is "DMX".
-
-
-
-2. Syntactic conventions
-
-    This document uses the same syntactic conventions requests and data
-    types as [X11R6.4].
-
-
-
-3. Data types
-
-    No new data types are defined by this extension.  All data types
-    referenced in this document are defined in [X11R6.4].

-
-4. Requests
-
-    DMXQueryVersion
-        ==>
-        majorVersion: CARD32
-        minorVersion: CARD32
-        patchVersion: CARD32
-
-    The protocol this extension actually supports is indicated by
-    majorVersion and minorVersion (patchVersion indicates the
-    patchlevel and is for informational purposes only).
-
-    Any incompatible changes to the protocol should be indicated by
-    incrementing majorVersion.
-
-    Small, upward-compatible changes should be indicated by incrementing
-    minorVersion.
-
-    Servers that support the protocol defined in this document will
-    return a majorVersion of 1 and a minorVersion of 1.
-
-
-
-    DMXGetScreenCount
-        ==>
-        screenCount: CARD32
-
-    This request returns the number of back-end screens that the Xdmx
-    server controls.  A back-end screen may be managed as a regular X
-    screen in the Xdmx server or may be joined with other back-end
-    screens using Xinerama.  (The information returned by this request
-    does not change while Xdmx is running and may be cached on the
-    client side.)
-    
-
-
-    DMXGetScreenInformation
-        physicalScreen: CARD32
-        ==>
-        displayName: STRING8
-        width: CARD16
-        height: CARD16
-        xoffset: INT16
-        yoffset: INT16
-        logicalScreen: CARD32
-        xorigin: INT16
-        yorigin: INT16
-
-        Errors: Value
-
-    This request returns information about individual back-end screens.
-    The physicalScreen value is between 0 and screenCount-1, inclusive
-    (values outside this range will result in a Value error).  The
-    displayname is the name used to open the display, either from the
-    Xdmx command-line or from the configuration file.  The width,
-    height, xoffset, and yoffset values comprise a geometry
-    specification (see X(7x)) for the location of the DMX window on the
-    back-end screen.  This request will always return non-negative
-    (i.e., normalized) values for xoffset and yoffset.  The
-    logicalScreen value is the value of the screen that that Xdmx server
-    exports to clients.  When Xinerama is in use, this value is
-    typically 0 for all values of physicalScreen.  If Xinerama is in
-    use, the xorigin and yorigin values specify where the physical
-    screen is positioned in the global Xinerama coordinate system.
-    Otherwise, these values are set to 0.  (The information returned by
-    this request does not change while Xdmx is running and may be cached
-    on the client side.)

-    DMXGetWindowInformation
-        window: CARD32
-        ==>
-        screenCount: CARD32
-        screens: LISTofCARD32
-        windows: LISTofCARD32
-        pos: LISTofRECTANGLE
-        vis: LISTofRECTANGLE
-
-        Errors: Window, Alloc
-
-    This request computed the return values incorrectly for version 1.0
-    of this protocol.  Version 1.1 of this protocol conforms to this
-    description.
-
-    Given a window ID on the Xdmx server, this request returns data
-    about how the window is represented on the back-end X servers.  For
-    each back-end X server that displays a portion of the window, the
-    following information is returned:
-        1) the number of the physical screen containing that portion
-           (which can be used with the DMXGetScreenInformation request
-           to obtain more information about the screen),
-        2) the window ID on the back-end X server of the window
-           containing that portion,
-        3) the position and dimensions of the window on the back-end, in
-           screen coordinates, and
-        4) the visible area of the window on the back-end, in
-           window-relative coordinates (all zeros for windows that are
-           not visible)
-    Note that DMX allows multiple back-end windows to overlap in their
-    view of the DMX logical window.  Further, a logical window does not
-    have to be completely covered by back-end windows -- there may be
-    gaps.
-
-    As an example, consider a 500x500 window that spans the top two
-    1024x768 back-end displays (A and B) of a 2048x1536 DMX display
-    composed of 4 1024x768 back-end displays arranged in a cube:
-        A B
-        C D
-
-    In this case, the DMXGetWindowInformation call would return the
-    following information for the 500x500 window:
-
-    display A: 500x500 window at 1024-250,0 (relative to back end)
-               with 250x500 visible at 0,0 (relative to window origin)
-
-    display B: 500x500 window at -250,0 (relative to back end)
-               with 250x500 visible at 250,0 (relative to window origin)
-
-    display C: 500x500 window at 1024-250,-768 with 0x0 visible at 0,0
-
-    display D: 500x500 window at -250,-768 with 0x0 visible at 0,0
-
-    Note that if the specified window has not yet been mapped when
-    DMXGetWindowInformation is called, then a subsequent XMapWindow call
-    might be buffered in xlib while requests directly to the back-end X
-    servers are processed.  This race condition can be solved by calling
-    DMXSync before talking directly to the back-end X servers.

-
-    DMXGetInputCount
-        ==>
-        inputCount: CARD32
-
-    This request was first supported in version 1.1 of this protocol.
-
-    This request returns the number of input devices connected to the
-    Xdmx server.  This number is the same as that returned by
-    XListInputDevices, but is available even when the XInput extension
-    is not supported.
-
-
-
-    DMXGetInputInformation
-        deviceId: CARD32
-        ==>
-        inputType: CARD32
-        physicalScreen: CARD32
-        physicalId: CARD32
-        isCore: BOOL
-        sendsCore: BOOL
-        name: STRING8
-
-        Errors: Value
-
-    This request was first supported in version 1.1 of this protocol.
-
-    This request returns information about the specified input device
-    that cannot be obtained from the XListInputDeivices call.  The
-    deviceId is the same as that used by the XListInputDevices call, and
-    must be in the range 0 to inputCount-1, inclusive (values outside
-    this range will result in a Value error).
-
-    The value of inputType will always be value, and will be one of the
-    following values:
-        0 for local (and dummy) devices,
-        1 for console devices, and
-        2 for back-end devices.
-
-    For local devices, all other fields returned, except isCore and
-    sendsCore, are invalid.
-
-    For console devices, the physicalScreen and physicalID will be
-    invalid, and the name will return the name of the X server on which
-    the console window is displayed.
-
-    For back-end devices, the physicalScreen will identify the back-end
-    display and can be used as an argument to DMXGetScreenInformation to
-    obtain more information; the physicalId will be the XInput device id
-    on the back-end X server; and the name will be invalid (since it
-    does not provide any additional information that cannot be obtained
-    with DMXGetScreenInformation).
-
-    If isCore is True, then this device is active as a true core input
-    device and will send core events.  If sendsCore is True, then this
-    device queried an XInput extension device, but sends core events
-    instead of extension events.  Note that this behavior is different
-    from that of XFree86, where XInput extension devices may send both
-    extension events and core events.

-
-    DMXForceWindowCreation
-        window: CARD32
-        ==>
-
-        Errors: Window
-
-    This request was first supported in version 1.2 of this protocol.
-
-    When using the lazy window creation optimization, windows are not
-    created on the back-end X servers until they are required.  This
-    request forces the immediate creation of the window requested.
-
-
-
-    DMXReconfigureScreen
-        screen: CARD32
-        x: INT16
-        y: INT16
-        ==>
-        status: CARD32
-
-        Errors: Value
-
-    This request was first supported in version 1.3 of this protocol.
-
-    This request reconfigures the screen position to coordinates (x,y)
-    when using the Xinerama extension.  Otherwise, it is a NOP.  Illegal
-    values for screen will result in a BadValue error.  Other non-fatal
-    errors will be returned in status.
-
-
-
-    DMXSync
-        ==>
-
-    This request was first supported in version 1.5 of this protocol.
-
-    This request flushes all pending protocol requests between the Xdmx
-    server and each back-end X server.  It is used by a client that
-    talks directly to back-end X servers
-
-    To ensure proper synchronization semantics, this request has a
-    reply, but the reply does not carry any information.

+
+1. Overview
+
+    The client-to-server DMX extension to the X protocol (DMX) provides
+    normal client applications with the ability to determine information
+    about the characteristics of the Xdmx server and the back-end X
+    servers that DMX is using.
+
+    The name for this extension is "DMX".
+
+
+
+2. Syntactic conventions
+
+    This document uses the same syntactic conventions requests and data
+    types as [X11R6.4].
+
+
+
+3. Data types
+
+    No new data types are defined by this extension.  All data types
+    referenced in this document are defined in [X11R6.4].
+
+
+
+4. Requests
+
+    DMXQueryVersion
+        ==>
+        majorVersion: CARD32
+        minorVersion: CARD32
+        patchVersion: CARD32
+
+    The protocol this extension actually supports is indicated by
+    majorVersion and minorVersion (patchVersion indicates the
+    patchlevel and is for informational purposes only).
+
+    Any incompatible changes to the protocol should be indicated by
+    incrementing majorVersion.
+
+    Small, upward-compatible changes should be indicated by incrementing
+    minorVersion.
+
+    Servers that support the protocol defined in this document will
+    return a majorVersion of 1 and a minorVersion of 1.
+
+
+
+    DMXGetScreenCount
+        ==>
+        screenCount: CARD32
+
+    This request returns the number of back-end screens that the Xdmx
+    server controls.  A back-end screen may be managed as a regular X
+    screen in the Xdmx server or may be joined with other back-end
+    screens using Xinerama.  (The information returned by this request
+    does not change while Xdmx is running and may be cached on the
+    client side.)
+    
+
+
+    DMXGetScreenInformation
+        physicalScreen: CARD32
+        ==>
+        displayName: STRING8
+        width: CARD16
+        height: CARD16
+        xoffset: INT16
+        yoffset: INT16
+        logicalScreen: CARD32
+        xorigin: INT16
+        yorigin: INT16
+
+        Errors: Value
+
+    This request returns information about individual back-end screens.
+    The physicalScreen value is between 0 and screenCount-1, inclusive
+    (values outside this range will result in a Value error).  The
+    displayname is the name used to open the display, either from the
+    Xdmx command-line or from the configuration file.  The width,
+    height, xoffset, and yoffset values comprise a geometry
+    specification (see X(7x)) for the location of the DMX window on the
+    back-end screen.  This request will always return non-negative
+    (i.e., normalized) values for xoffset and yoffset.  The
+    logicalScreen value is the value of the screen that that Xdmx server
+    exports to clients.  When Xinerama is in use, this value is
+    typically 0 for all values of physicalScreen.  If Xinerama is in
+    use, the xorigin and yorigin values specify where the physical
+    screen is positioned in the global Xinerama coordinate system.
+    Otherwise, these values are set to 0.  (The information returned by
+    this request does not change while Xdmx is running and may be cached
+    on the client side.)
+
+
+
+    DMXGetWindowInformation
+        window: CARD32
+        ==>
+        screenCount: CARD32
+        screens: LISTofCARD32
+        windows: LISTofCARD32
+        pos: LISTofRECTANGLE
+        vis: LISTofRECTANGLE
+
+        Errors: Window, Alloc
+
+    This request computed the return values incorrectly for version 1.0
+    of this protocol.  Version 1.1 of this protocol conforms to this
+    description.
+
+    Given a window ID on the Xdmx server, this request returns data
+    about how the window is represented on the back-end X servers.  For
+    each back-end X server that displays a portion of the window, the
+    following information is returned:
+        1) the number of the physical screen containing that portion
+           (which can be used with the DMXGetScreenInformation request
+           to obtain more information about the screen),
+        2) the window ID on the back-end X server of the window
+           containing that portion,
+        3) the position and dimensions of the window on the back-end, in
+           screen coordinates, and
+        4) the visible area of the window on the back-end, in
+           window-relative coordinates (all zeros for windows that are
+           not visible)
+    Note that DMX allows multiple back-end windows to overlap in their
+    view of the DMX logical window.  Further, a logical window does not
+    have to be completely covered by back-end windows -- there may be
+    gaps.
+
+    As an example, consider a 500x500 window that spans the top two
+    1024x768 back-end displays (A and B) of a 2048x1536 DMX display
+    composed of 4 1024x768 back-end displays arranged in a cube:
+        A B
+        C D
+
+    In this case, the DMXGetWindowInformation call would return the
+    following information for the 500x500 window:
+
+    display A: 500x500 window at 1024-250,0 (relative to back end)
+               with 250x500 visible at 0,0 (relative to window origin)
+
+    display B: 500x500 window at -250,0 (relative to back end)
+               with 250x500 visible at 250,0 (relative to window origin)
+
+    display C: 500x500 window at 1024-250,-768 with 0x0 visible at 0,0
+
+    display D: 500x500 window at -250,-768 with 0x0 visible at 0,0
+
+    Note that if the specified window has not yet been mapped when
+    DMXGetWindowInformation is called, then a subsequent XMapWindow call
+    might be buffered in xlib while requests directly to the back-end X
+    servers are processed.  This race condition can be solved by calling
+    DMXSync before talking directly to the back-end X servers.
+
+
+    DMXGetInputCount
+        ==>
+        inputCount: CARD32
+
+    This request was first supported in version 1.1 of this protocol.
+
+    This request returns the number of input devices connected to the
+    Xdmx server.  This number is the same as that returned by
+    XListInputDevices, but is available even when the XInput extension
+    is not supported.
+
+
+
+    DMXGetInputInformation
+        deviceId: CARD32
+        ==>
+        inputType: CARD32
+        physicalScreen: CARD32
+        physicalId: CARD32
+        isCore: BOOL
+        sendsCore: BOOL
+        name: STRING8
+
+        Errors: Value
+
+    This request was first supported in version 1.1 of this protocol.
+
+    This request returns information about the specified input device
+    that cannot be obtained from the XListInputDeivices call.  The
+    deviceId is the same as that used by the XListInputDevices call, and
+    must be in the range 0 to inputCount-1, inclusive (values outside
+    this range will result in a Value error).
+
+    The value of inputType will always be value, and will be one of the
+    following values:
+        0 for local (and dummy) devices,
+        1 for console devices, and
+        2 for back-end devices.
+
+    For local devices, all other fields returned, except isCore and
+    sendsCore, are invalid.
+
+    For console devices, the physicalScreen and physicalID will be
+    invalid, and the name will return the name of the X server on which
+    the console window is displayed.
+
+    For back-end devices, the physicalScreen will identify the back-end
+    display and can be used as an argument to DMXGetScreenInformation to
+    obtain more information; the physicalId will be the XInput device id
+    on the back-end X server; and the name will be invalid (since it
+    does not provide any additional information that cannot be obtained
+    with DMXGetScreenInformation).
+
+    If isCore is True, then this device is active as a true core input
+    device and will send core events.  If sendsCore is True, then this
+    device queried an XInput extension device, but sends core events
+    instead of extension events.  Note that this behavior is different
+    from that of XFree86, where XInput extension devices may send both
+    extension events and core events.
+
+
+
+    DMXForceWindowCreation
+        window: CARD32
+        ==>
+
+        Errors: Window
+
+    This request was first supported in version 1.2 of this protocol.
+
+    When using the lazy window creation optimization, windows are not
+    created on the back-end X servers until they are required.  This
+    request forces the immediate creation of the window requested.
+
+
+
+    DMXReconfigureScreen
+        screen: CARD32
+        x: INT16
+        y: INT16
+        ==>
+        status: CARD32
+
+        Errors: Value
+
+    This request was first supported in version 1.3 of this protocol.
+
+    This request reconfigures the screen position to coordinates (x,y)
+    when using the Xinerama extension.  Otherwise, it is a NOP.  Illegal
+    values for screen will result in a BadValue error.  Other non-fatal
+    errors will be returned in status.
+
+
+
+    DMXSync
+        ==>
+
+    This request was first supported in version 1.5 of this protocol.
+
+    This request flushes all pending protocol requests between the Xdmx
+    server and each back-end X server.  It is used by a client that
+    talks directly to back-end X servers
+
+    To ensure proper synchronization semantics, this request has a
+    reply, but the reply does not carry any information.

-1. Overview
-
-    The client-to-server DMX extension to the X protocol (DMX) provides
-    normal client applications with the ability to determine information
-    about the characteristics of the Xdmx server and the back-end X
-    servers that DMX is using.
-
-    The name for this extension is "DMX".
-
-
-
-2. Syntactic conventions
-
-    This document uses the same syntactic conventions requests and data
-    types as [X11R6.4].
-
-
-
-3. Data types
-
-    No new data types are defined by this extension.  All data types
-    referenced in this document are defined in [X11R6.4].
-
-
-
-4. Requests
-
-    DMXQueryVersion
-        ==>
-        majorVersion: CARD32
-        minorVersion: CARD32
-        patchVersion: CARD32
-
-        Errors: None
-
-    The protocol this extension actually supports is indicated by
-    majorVersion and minorVersion (patchVersion indicates the
-    patchlevel and is for informational purposes only).
-
-    Any incompatible changes to the protocol should be indicated by
-    incrementing majorVersion.
-
-    Small, upward-compatible changes should be indicated by incrementing
-    minorVersion.
-
-    Servers that support the protocol defined in this document will
-    return a majorVersion of 2 and a minorVersion of 2.
-
-    (Version 1.5 was the last version in the 1.x series; version 2.0 was
-    a testing version that was poorly defined.)
-
-
-
-    DMXSync
-        ==>
-        status: CARD32
-
-        Errors: None
-
-    This request was first supported in version 1.5 of this protocol.
-    The status field in the reply was introduced in version 2.0 of this
-    protocol.  Since the status field is ignored, no changes to the
-    underlying protocol were required.
-
-    This request flushes all pending protocol requests between the Xdmx
-    server and each back-end X server.  It is used by clients that
-    talk directly to back-end X servers to ensure that all pending Xdmx
-    requests have reached all back-end servers and have been processed
-    by those servers.
-
-    The value of status is always 0.
-
-
-
-    DMXForceWindowCreation
-        window: CARD32
-        ==>
-        status: CARD32
-
-        Errors: Window
-
-    This request was first supported in version 1.2 of this protocol.
-    This request was changed to have a reply in version 2.0 of this
-    protocol.  The old version of this request was deprecated and will
-    return BadImplementation.
-
-    When using the lazy window creation optimization, windows are not
-    created on the back-end X servers until they are required.  This
-    request forces the immediate creation of the window requested.
-
-    The value of status is always 0.
-
-
-
-
-    DMXGetScreenCount
-        ==>
-        screenCount: CARD32
-
-        Errors: None
-
-    This request returns the number of screens that the Xdmx server
-    controls.  Since a DMX screen usually fills all of the available
-    area on a back-end server, there is usually a one-to-one
-    correspondence between DMX screens and backend servers.  However, it
-    is also possible for a DMX screen to cover only part of the
-    available area on a back-end server, and for more than one DMX
-    screen to occupy different parts of the visible area on the same
-    back-end server.
-
-    A DMX screen may be managed as a regular X screen in the Xdmx server
-    or may be joined with other DMX screens using Xinerama.
-    
-
-
-    DMXGetScreenAttributes
-        physicalScreen: CARD32
-        ==>
-        displayName: STRING8
-        logicalScreen: CARD32
-        screenWindowWidth: CARD16
-        screenWindowHeight: CARD16
-        screenWindowXoffset: INT16
-        screenWindowYoffset: INT16
-        rootWindowWidth: CARD16
-        rootWindowHeight: CARD16
-        rootWindowXoffset: INT16
-        rootWindowYoffset: INT16
-        rootWindowXorigin: INT16
-        rootWindowYorigin: INT16
-
-        Errors: Value
-
-    This request is new in version 2.0 of this protocol.  The old
-    DMXGetScreenInformation request is deprecated and will now return
-    BadImplementation.
-
-    This request returns attributes about a single DMX screen.
-
-    The physicalScreen value is between 0 and screenCount-1, inclusive
-    (values outside this range will result in a Value error).
-
-    The displayname is the name used to open the display, either from
-    the Xdmx command-line or from the configuration file.
-
-    The logicalScreen value is the value of the screen that that Xdmx
-    server exports to clients.  When Xinerama is in use, this value is
-    typically 0 for all values of physicalScreen.  If Xinerama is in
-    use, the rootWindowXOrigin and rootWindowYOrigin values specify
-    where the physical screen is positioned in the global Xinerama
-    coordinate system.  Otherwise, these values are set to 0.
-
-    The screenWindow values comprise a geometry specification (see
-    X(7x)) for the location of the DMX screen on the back-end screen.
-    The coordinant system of the back-end display is used.
-
-    The first four rootWindow values comprise a geometry specification
-    (see X(7x)) for the location of the root window on the screen
-    window.  The coordinant system of the screen window is used.  In
-    most cases, the root window will have the same geometry as the DMX
-    screen window, and will occupy the same area of the back-end
-    display.  (This would not be the case, for example, if automatic
-    projector alignment is used.)

-        status: CARD32
-        errorScreen: CARD32
-
-        Errors: Length, Alloc
-
-    This request was first supported in version 2.0 of this protocol.
-    (A singular version of this request with the ability to change some
-    RootWindow attributes was supported in version 1.3 of this protocol,
-    has been deprecated, and will return BadImplementation.)
-
-    This request changes the geometries and positions of the DMX screen
-    and DMX root windows on the back-end X servers.
-   
-    The valueMask and valueList specify which attributes are to be
-    changed.  The possible values are:
-
-        Attribute               Type
-
-        ScreenWindowWidth       CARD16
-        ScreenWindowHeight      CARD16
-        ScreenWindowXoffset     INT16
-        ScreenWindowYoffset     INT16
-        RootWindowWidth         CARD16
-        RootWindowHeight        CARD16
-        RootWindowXoffset       INT16
-        RootWindowYoffset       INT16
-        RootWindowXorigin       INT16
-        RootWindowYorigin       INT16
-
-    The attribute values have the same meaning as do the corresponding
-    values for DMXGetScreenAttributes.
-
-    Non-fatal errors will be returned in status (0 otherwise):
-        DmxBadXinerama: Xinerama is not active
-        DmxBadValue:    The resulting position is not allowed
-                        (e.g., one corner is outside the bounding box)
-    On error, errorScreen will contain the number of the screen that
-    caused the first error.
-
-
-
-    DMXAddScreen
-        displayName: STRING8
-        physicalScreen: CARD32
-        valueMask: CARD32
-        valueList: LISTofVALUES
-        ==>
-        status: CARD32
-        physicalScreen: CARD32
-
-        Errors: Length, Alloc, Value
-
-    This request was first supported in version 2.2 of this protocol.
-
-    This request re-attaches the back-end physicalScreen to the Xdmx
-    server.  Only back-end screens that have been previously detached
-    with DMXRemoveScreen may be added.  The name of the back-end display
-    is given in displayName, and this will replace the name of the
-    back-end screen that was detached.  Both the displayName and
-    physicalScreen must be correct for this request to work.
-
-    The valueMask and valueList specify the attributes to be used.  The
-    possible values are:
-
-        Attribute               Type
-
-        ScreenWindowWidth       CARD16
-        ScreenWindowHeight      CARD16
-        ScreenWindowXoffset     INT16
-        ScreenWindowYoffset     INT16
-        RootWindowWidth         CARD16
-        RootWindowHeight        CARD16
-        RootWindowXoffset       INT16
-        RootWindowYoffset       INT16
-        RootWindowXorigin       INT16
-        RootWindowYorigin       INT16
-
-    The attribute values have the same meaning as do the corresponding
-    values for DMXGetScreenAttributes.
-
-    On success, status will be 0 and physicalScreen will contain the new
-    screen number.  On failure, status will be non-zero.  The status
-    will be 1 if any of the following occured:
-        * the -addremovescreens command-line option was not specified on
-          the Xdmx command line
-        * the value of physicalScreen is out of range
-        * physicalScreen has not been detached (with DMXRemoveScreen)
-        * displayName cannot be opened
-        * the visuals of displayname do not match the visuals that Xdmx
-          is using
-        * the screen data for displayName does not match the data for the
-          previously removed display
-    The status will be DmxBadValue if the attribute values are out of
-    range.
-

-    DMXRemoveScreen
-        physicalScreen: CARD32
-        ==>
-        status: CARD32
-
-        Errors: None
-
-    This request was first supported in version 2.2 of this protocol.
-
-    This request detaches the physicalScreen screen.
-
-    On success, status will be 0.  On failure, the status will 1 if any
-    of the following occur:
-        * the -addremovescreens command-line option was not specified on
-          the Xdmx command line
-        * the value of physicalScreen is out of range
-        * the back-end screen has already been detached.

-        vis: LISTofRECTANGLE
-
-        Errors: Window, Alloc
-
-    This request computes the return values incorrectly for version 1.0
-    of this protocol.  Version 1.1 of this protocol conforms to this
-    description.  In version 2.0, the name of this request was changed
-    from DMXGetWindowInformation.  However, since the request itself did
-    not change, no changes to the underlying protocol were made.
-
-    Given a window ID on the Xdmx server, this request returns data
-    about how the window is represented on the back-end X servers.  For
-    each back-end X server that displays a portion of the window, the
-    following information is returned:
-        1) the number of the physical screen containing that portion
-           (which can be used with the DMXGetScreenAttributes request
-           to obtain more information about the screen),
-        2) the window ID on the back-end X server of the window
-           containing that portion,
-        3) the position and dimensions of the window on the back-end, in
-           screen coordinates, and
-        4) the visible area of the window on the back-end, in
-           window-relative coordinates (all zeros for windows that are
-           not visible).
-    Note that DMX allows multiple back-end windows to overlap in their
-    view of the DMX logical window.  Further, a logical window does not
-    have to be completely covered by back-end windows -- there may be
-    gaps.
-
-    As an example, consider a 500x500 window that spans the top two
-    1024x768 back-end displays (A and B) of a 2048x1536 DMX display
-    composed of 4 1024x768 back-end displays arranged in a cube:
-        A B
-        C D
-
-    In this case, the DMXGetWindowAttributes call would return the
-    following information for the 500x500 window:
-
-    display A: 500x500 window at 1024-250,0 (relative to back end)
-               with 250x500 visible at 0,0 (relative to window origin)
-
-    display B: 500x500 window at -250,0 (relative to back end)
-               with 250x500 visible at 250,0 (relative to window origin)
-
-    display C: 500x500 window at 1024-250,-768 with 0x0 visible at 0,0
-
-    display D: 500x500 window at -250,-768 with 0x0 visible at 0,0
-
-    Note that if the specified window has not yet been mapped when
-    DMXGetWindowAttributes is called, then a subsequent XMapWindow call
-    might be buffered in xlib while requests directly to the back-end X
-    servers are processed.  This race condition can be solved by calling
-    DMXSync before talking directly to the back-end X servers.

-
-        Errors: None
-
-    This request was first supported in version 2.0 of this protocol.
-
-    This request returns the size of the bounding box of the whole
-    screen in width and height.  The shiftX and shiftY values will
-    always be 0.  The global bounding box is computed whether or not
-    Xinerama is active, and may be larger than the Xinerama screen size
-    because of information in the configuration file.

-
-        Errors: Length, Value
-
-    This request was first supported in version 2.0 of this protocol.
-
-    This request resizes the bounding box of the whole screen when using
-    the Xinerama extension.  Otherwise, it has no effect on the screen
-    layout.  The valueMask and valueList specify which attributes are to
-    be changed.  The possible values are:
-
-        Attriubute      Type
-
-        Width           INT16
-        Height          INT16
-        ShiftX          INT16
-        ShiftY          INT16
-
-    Width and Height specify the new width and height for the bounding
-    box.  ShiftX and ShiftY specify where the Xinerama origin will be
-    placed with respect to the origin of the new bounding box.  This
-    allows the left and upper edges of the bounding box to be changed
-    without changing the visual position of the windows on the desktop.
-    If Width or Height is not specified, the current values will be
-    used.  If ShiftX or ShiftY is not specified, 0 will be used.
-
-    All coordinants are in the global DMX coordinant system.  If
-    Xinerama is not active, this request is not useful.
-
-    Non-fatal errors will be returned in status (0 otherwise):
-        DmxBadXinerama: Xinerama is not active
-        DmxBadValue:    The size of the bounding box is too large
-
-
-
-    DMXGetInputCount
-        ==>
-        inputCount: CARD32
-
-    This request was first supported in version 1.1 of this protocol.
-
-    This request returns the number of input devices connected to the
-    Xdmx server.  This number is the same as that returned by
-    XListInputDevices, but is available even when the XInput extension
-    is not supported.
-

-        sendsCore: BOOL
-        detached: BOOL
-        name: STRING8
-
-        Errors: Value
-
-    This request was first supported in version 1.1 of this protocol.
-    In version 2.0, the name of this request was changed from
-    DMXGetInputInformation.  However, since the request itself did not
-    change, no changes to the underlying protocol were made.  In version
-    2.2, the name of detached was changed from reservation.  There was
-    no change in underlying protocol.
-
-    This request returns information about the specified input device
-    that cannot be obtained from the XListInputDeivices call.  The
-    deviceId is the same as that used by the XListInputDevices call, and
-    must be in the range 0 to inputCount-1, inclusive (values outside
-    this range will result in a Value error).
-
-    The value of inputType will always be valid, and will be one of the
-    following values:
-        0 for local (and dummy) devices,
-        1 for console devices, and
-        2 for back-end devices.
-
-    For local devices, all other fields returned, except isCore and
-    sendsCore, are invalid.
-
-    For console devices, the physicalScreen and physicalID will be
-    invalid, and the name will return the name of the X server on which
-    the console window is displayed.
-
-    For back-end devices, the physicalScreen will identify the back-end
-    display and can be used as an argument to DMXGetScreenAttributes to
-    obtain more information; the physicalId will be the XInput device id
-    on the back-end X server; and the name will be invalid (since it
-    does not provide any additional information that cannot be obtained
-    with DMXGetScreenAttributes).
-
-    If isCore is True, then this device is active as a true core input
-    device and will send core events.  If sendsCore is True, then this
-    device is an XInput extension device, but sends core events instead
-    of extension events.  Note that this behavior is different from that
-    of XFree86 or Xorg, where XInput extension devices may send both
-    extension events and core events.
-
-    If detached is True, then this device has been detached and is no
-    longer producing input events.  The device may be reattached using
-    DMXAddInput.

-    This request was first supported in version 2.2 of this protocol.
-
-    The valueMask and valueList specify the attributes to be used.  The
-    possible values are:
-
-        Attribute               Type
-
-        InputType               CARD32
-        InputPhysicalScreen     CARD32
-        InputSendsCore          BOOL
-
-    This request attaches an input device to the Xdmx server.  The value
-    of inputType will be one:
-        1 for console devices, and
-        2 for back-end devices.
-    Other values of InputType will return a BadValue error.  Local
-    devices (inputType=0 in DMXGetInputAttributes) cannot be attached or
-    removed.  For console devices, displayName will store the name of
-    the display to be used.
-
-    For back-end devices, InputPhysicalScreen will specify the screen
-    number.  BadValue will be returned if the screen number is out of
-    range.  BadAccess will be returned if the input has already been
-    attached or if the backend screen is currently detached.
-
-    If InputSendsCore is True, the new device will be added as a true
-    core device.
-
-    If a device was removed with DMXRemoveInput an attempt will be made
-    to reconnect the previous devices (InputSendsCore is ignored in this
-    case).

-        Errors: Value, Access
-
-    This request was first supported in version 2.2 of this protocol.
-
-    This request detaches the input device with physicalId, and all
-    associated inputs (e.g., if the physicalId is a backend mouse, and a
-    keyboard is also attached to the backend, then both devices will be
-    detached).  If the physicalId is outside the valid range (0 to one
-    less than the value returned by DMXInputCount), BadValue is
-    returned.  If the physicalId has already been detached, BadAccess is
-    returned.  The status is always 0.

+
+1. Overview
+
+    The client-to-server DMX extension to the X protocol (DMX) provides
+    normal client applications with the ability to determine information
+    about the characteristics of the Xdmx server and the back-end X
+    servers that DMX is using.
+
+    The name for this extension is "DMX".
+
+
+
+2. Syntactic conventions
+
+    This document uses the same syntactic conventions requests and data
+    types as [X11R6.4].
+
+
+
+3. Data types
+
+    No new data types are defined by this extension.  All data types
+    referenced in this document are defined in [X11R6.4].
+
+
+
+4. Requests
+
+    DMXQueryVersion
+        ==>
+        majorVersion: CARD32
+        minorVersion: CARD32
+        patchVersion: CARD32
+
+        Errors: None
+
+    The protocol this extension actually supports is indicated by
+    majorVersion and minorVersion (patchVersion indicates the
+    patchlevel and is for informational purposes only).
+
+    Any incompatible changes to the protocol should be indicated by
+    incrementing majorVersion.
+
+    Small, upward-compatible changes should be indicated by incrementing
+    minorVersion.
+
+    Servers that support the protocol defined in this document will
+    return a majorVersion of 2 and a minorVersion of 2.
+
+    (Version 1.5 was the last version in the 1.x series; version 2.0 was
+    a testing version that was poorly defined.)
+
+
+
+    DMXSync
+        ==>
+        status: CARD32
+
+        Errors: None
+
+    This request was first supported in version 1.5 of this protocol.
+    The status field in the reply was introduced in version 2.0 of this
+    protocol.  Since the status field is ignored, no changes to the
+    underlying protocol were required.
+
+    This request flushes all pending protocol requests between the Xdmx
+    server and each back-end X server.  It is used by clients that
+    talk directly to back-end X servers to ensure that all pending Xdmx
+    requests have reached all back-end servers and have been processed
+    by those servers.
+
+    The value of status is always 0.
+
+
+
+    DMXForceWindowCreation
+        window: CARD32
+        ==>
+        status: CARD32
+
+        Errors: Window
+
+    This request was first supported in version 1.2 of this protocol.
+    This request was changed to have a reply in version 2.0 of this
+    protocol.  The old version of this request was deprecated and will
+    return BadImplementation.
+
+    When using the lazy window creation optimization, windows are not
+    created on the back-end X servers until they are required.  This
+    request forces the immediate creation of the window requested.
+
+    The value of status is always 0.
+
+
+
+
+    DMXGetScreenCount
+        ==>
+        screenCount: CARD32
+
+        Errors: None
+
+    This request returns the number of screens that the Xdmx server
+    controls.  Since a DMX screen usually fills all of the available
+    area on a back-end server, there is usually a one-to-one
+    correspondence between DMX screens and backend servers.  However, it
+    is also possible for a DMX screen to cover only part of the
+    available area on a back-end server, and for more than one DMX
+    screen to occupy different parts of the visible area on the same
+    back-end server.
+
+    A DMX screen may be managed as a regular X screen in the Xdmx server
+    or may be joined with other DMX screens using Xinerama.
+    
+
+
+    DMXGetScreenAttributes
+        physicalScreen: CARD32
+        ==>
+        displayName: STRING8
+        logicalScreen: CARD32
+        screenWindowWidth: CARD16
+        screenWindowHeight: CARD16
+        screenWindowXoffset: INT16
+        screenWindowYoffset: INT16
+        rootWindowWidth: CARD16
+        rootWindowHeight: CARD16
+        rootWindowXoffset: INT16
+        rootWindowYoffset: INT16
+        rootWindowXorigin: INT16
+        rootWindowYorigin: INT16
+
+        Errors: Value
+
+    This request is new in version 2.0 of this protocol.  The old
+    DMXGetScreenInformation request is deprecated and will now return
+    BadImplementation.
+
+    This request returns attributes about a single DMX screen.
+
+    The physicalScreen value is between 0 and screenCount-1, inclusive
+    (values outside this range will result in a Value error).
+
+    The displayname is the name used to open the display, either from
+    the Xdmx command-line or from the configuration file.
+
+    The logicalScreen value is the value of the screen that that Xdmx
+    server exports to clients.  When Xinerama is in use, this value is
+    typically 0 for all values of physicalScreen.  If Xinerama is in
+    use, the rootWindowXOrigin and rootWindowYOrigin values specify
+    where the physical screen is positioned in the global Xinerama
+    coordinate system.  Otherwise, these values are set to 0.
+
+    The screenWindow values comprise a geometry specification (see
+    X(7x)) for the location of the DMX screen on the back-end screen.
+    The coordinant system of the back-end display is used.
+
+    The first four rootWindow values comprise a geometry specification
+    (see X(7x)) for the location of the root window on the screen
+    window.  The coordinant system of the screen window is used.  In
+    most cases, the root window will have the same geometry as the DMX
+    screen window, and will occupy the same area of the back-end
+    display.  (This would not be the case, for example, if automatic
+    projector alignment is used.)
+
+
+
+    DMXChangeScreensAttributes
+        screenCount: CARD32
+        maskCount: CARD32

+        ==>
+        status: CARD32
+        errorScreen: CARD32
+
+        Errors: Length, Alloc
+
+    This request was first supported in version 2.0 of this protocol.
+    (A singular version of this request with the ability to change some
+    RootWindow attributes was supported in version 1.3 of this protocol,
+    has been deprecated, and will return BadImplementation.)
+
+    This request changes the geometries and positions of the DMX screen
+    and DMX root windows on the back-end X servers.
+   
+    The valueMask and valueList specify which attributes are to be
+    changed.  The possible values are:
+
+        Attribute               Type
+
+        ScreenWindowWidth       CARD16
+        ScreenWindowHeight      CARD16
+        ScreenWindowXoffset     INT16
+        ScreenWindowYoffset     INT16
+        RootWindowWidth         CARD16
+        RootWindowHeight        CARD16
+        RootWindowXoffset       INT16
+        RootWindowYoffset       INT16
+        RootWindowXorigin       INT16
+        RootWindowYorigin       INT16
+
+    The attribute values have the same meaning as do the corresponding
+    values for DMXGetScreenAttributes.
+
+    Non-fatal errors will be returned in status (0 otherwise):
+        DmxBadXinerama: Xinerama is not active
+        DmxBadValue:    The resulting position is not allowed
+                        (e.g., one corner is outside the bounding box)
+    On error, errorScreen will contain the number of the screen that
+    caused the first error.
+
+
+
+    DMXAddScreen
+        displayName: STRING8
+        physicalScreen: CARD32
+        valueMask: CARD32
+        valueList: LISTofVALUES
+        ==>
+        status: CARD32
+        physicalScreen: CARD32
+
+        Errors: Length, Alloc, Value
+
+    This request was first supported in version 2.2 of this protocol.
+
+    This request re-attaches the back-end physicalScreen to the Xdmx
+    server.  Only back-end screens that have been previously detached
+    with DMXRemoveScreen may be added.  The name of the back-end display
+    is given in displayName, and this will replace the name of the
+    back-end screen that was detached.  Both the displayName and
+    physicalScreen must be correct for this request to work.
+
+    The valueMask and valueList specify the attributes to be used.  The
+    possible values are:
+
+        Attribute               Type
+
+        ScreenWindowWidth       CARD16
+        ScreenWindowHeight      CARD16
+        ScreenWindowXoffset     INT16
+        ScreenWindowYoffset     INT16
+        RootWindowWidth         CARD16
+        RootWindowHeight        CARD16
+        RootWindowXoffset       INT16
+        RootWindowYoffset       INT16
+        RootWindowXorigin       INT16
+        RootWindowYorigin       INT16
+
+    The attribute values have the same meaning as do the corresponding
+    values for DMXGetScreenAttributes.
+
+    On success, status will be 0 and physicalScreen will contain the new
+    screen number.  On failure, status will be non-zero.  The status
+    will be 1 if any of the following occured:
+        * the -addremovescreens command-line option was not specified on
+          the Xdmx command line
+        * the value of physicalScreen is out of range
+        * physicalScreen has not been detached (with DMXRemoveScreen)
+        * displayName cannot be opened
+        * the visuals of displayname do not match the visuals that Xdmx
+          is using
+        * the screen data for displayName does not match the data for the
+          previously removed display
+    The status will be DmxBadValue if the attribute values are out of
+    range.
+
+
+
+    DMXRemoveScreen
+        physicalScreen: CARD32
+        ==>
+        status: CARD32
+
+        Errors: None
+
+    This request was first supported in version 2.2 of this protocol.
+
+    This request detaches the physicalScreen screen.
+
+    On success, status will be 0.  On failure, the status will 1 if any
+    of the following occur:
+        * the -addremovescreens command-line option was not specified on
+          the Xdmx command line
+        * the value of physicalScreen is out of range
+        * the back-end screen has already been detached.
+
+
+
+    DMXGetWindowAttributes
+        window: CARD32
+        ==>
+        screenCount: CARD32
+        screens: LISTofCARD32
+        windows: LISTofCARD32
+        pos: LISTofRECTANGLE
+        vis: LISTofRECTANGLE
+
+        Errors: Window, Alloc
+
+    This request computes the return values incorrectly for version 1.0
+    of this protocol.  Version 1.1 of this protocol conforms to this
+    description.  In version 2.0, the name of this request was changed
+    from DMXGetWindowInformation.  However, since the request itself did
+    not change, no changes to the underlying protocol were made.
+
+    Given a window ID on the Xdmx server, this request returns data
+    about how the window is represented on the back-end X servers.  For
+    each back-end X server that displays a portion of the window, the
+    following information is returned:
+        1) the number of the physical screen containing that portion
+           (which can be used with the DMXGetScreenAttributes request
+           to obtain more information about the screen),
+        2) the window ID on the back-end X server of the window
+           containing that portion,
+        3) the position and dimensions of the window on the back-end, in
+           screen coordinates, and
+        4) the visible area of the window on the back-end, in
+           window-relative coordinates (all zeros for windows that are
+           not visible).
+    Note that DMX allows multiple back-end windows to overlap in their
+    view of the DMX logical window.  Further, a logical window does not
+    have to be completely covered by back-end windows -- there may be
+    gaps.
+
+    As an example, consider a 500x500 window that spans the top two
+    1024x768 back-end displays (A and B) of a 2048x1536 DMX display
+    composed of 4 1024x768 back-end displays arranged in a cube:
+        A B
+        C D
+
+    In this case, the DMXGetWindowAttributes call would return the
+    following information for the 500x500 window:
+
+    display A: 500x500 window at 1024-250,0 (relative to back end)
+               with 250x500 visible at 0,0 (relative to window origin)
+
+    display B: 500x500 window at -250,0 (relative to back end)
+               with 250x500 visible at 250,0 (relative to window origin)
+
+    display C: 500x500 window at 1024-250,-768 with 0x0 visible at 0,0
+
+    display D: 500x500 window at -250,-768 with 0x0 visible at 0,0
+
+    Note that if the specified window has not yet been mapped when
+    DMXGetWindowAttributes is called, then a subsequent XMapWindow call
+    might be buffered in xlib while requests directly to the back-end X
+    servers are processed.  This race condition can be solved by calling
+    DMXSync before talking directly to the back-end X servers.

+
+        Errors: None
+
+    This request was first supported in version 2.0 of this protocol.
+
+    This request returns the size of the bounding box of the whole
+    screen in width and height.  The shiftX and shiftY values will
+    always be 0.  The global bounding box is computed whether or not
+    Xinerama is active, and may be larger than the Xinerama screen size
+    because of information in the configuration file.

+
+        Errors: Length, Value
+
+    This request was first supported in version 2.0 of this protocol.
+
+    This request resizes the bounding box of the whole screen when using
+    the Xinerama extension.  Otherwise, it has no effect on the screen
+    layout.  The valueMask and valueList specify which attributes are to
+    be changed.  The possible values are:
+
+        Attriubute      Type
+
+        Width           INT16
+        Height          INT16
+        ShiftX          INT16
+        ShiftY          INT16
+
+    Width and Height specify the new width and height for the bounding
+    box.  ShiftX and ShiftY specify where the Xinerama origin will be
+    placed with respect to the origin of the new bounding box.  This
+    allows the left and upper edges of the bounding box to be changed
+    without changing the visual position of the windows on the desktop.
+    If Width or Height is not specified, the current values will be
+    used.  If ShiftX or ShiftY is not specified, 0 will be used.
+
+    All coordinants are in the global DMX coordinant system.  If
+    Xinerama is not active, this request is not useful.
+
+    Non-fatal errors will be returned in status (0 otherwise):
+        DmxBadXinerama: Xinerama is not active
+        DmxBadValue:    The size of the bounding box is too large
+
+
+
+    DMXGetInputCount
+        ==>
+        inputCount: CARD32
+
+    This request was first supported in version 1.1 of this protocol.
+
+    This request returns the number of input devices connected to the
+    Xdmx server.  This number is the same as that returned by
+    XListInputDevices, but is available even when the XInput extension
+    is not supported.
+
+

+        sendsCore: BOOL
+        detached: BOOL
+        name: STRING8
+
+        Errors: Value
+
+    This request was first supported in version 1.1 of this protocol.
+    In version 2.0, the name of this request was changed from
+    DMXGetInputInformation.  However, since the request itself did not
+    change, no changes to the underlying protocol were made.  In version

+    no change in underlying protocol.
+
+    This request returns information about the specified input device
+    that cannot be obtained from the XListInputDeivices call.  The
+    deviceId is the same as that used by the XListInputDevices call, and
+    must be in the range 0 to inputCount-1, inclusive (values outside
+    this range will result in a Value error).
+
+    The value of inputType will always be valid, and will be one of the
+    following values:
+        0 for local (and dummy) devices,
+        1 for console devices, and
+        2 for back-end devices.
+
+    For local devices, all other fields returned, except isCore and
+    sendsCore, are invalid.
+
+    For console devices, the physicalScreen and physicalID will be
+    invalid, and the name will return the name of the X server on which
+    the console window is displayed.
+
+    For back-end devices, the physicalScreen will identify the back-end
+    display and can be used as an argument to DMXGetScreenAttributes to
+    obtain more information; the physicalId will be the XInput device id
+    on the back-end X server; and the name will be invalid (since it
+    does not provide any additional information that cannot be obtained
+    with DMXGetScreenAttributes).
+
+    If isCore is True, then this device is active as a true core input
+    device and will send core events.  If sendsCore is True, then this
+    device is an XInput extension device, but sends core events instead
+    of extension events.  Note that this behavior is different from that
+    of XFree86 or Xorg, where XInput extension devices may send both
+    extension events and core events.
+
+    If detached is True, then this device has been detached and is no
+    longer producing input events.  The device may be reattached using
+    DMXAddInput.

+
+        InputType               CARD32

+
+    This request attaches an input device to the Xdmx server.  The value
+    of inputType will be one:
+        1 for console devices, and
+        2 for back-end devices.
+    Other values of InputType will return a BadValue error.  Local
+    devices (inputType=0 in DMXGetInputAttributes) cannot be attached or
+    removed.  For console devices, displayName will store the name of
+    the display to be used.
+
+    For back-end devices, InputPhysicalScreen will specify the screen
+    number.  BadValue will be returned if the screen number is out of
+    range.  BadAccess will be returned if the input has already been
+    attached or if the backend screen is currently detached.
+
+    If InputSendsCore is True, the new device will be added as a true
+    core device.
+
+    If a device was removed with DMXRemoveInput an attempt will be made
+    to reconnect the previous devices (InputSendsCore is ignored in this
+    case).

+
+    This request was first supported in version 2.2 of this protocol.
+
+    This request detaches the input device with physicalId, and all
+    associated inputs (e.g., if the physicalId is a backend mouse, and a
+    keyboard is also attached to the backend, then both devices will be
+    detached).  If the physicalId is outside the valid range (0 to one
+    less than the value returned by DMXInputCount), BadValue is
+    returned.  If the physicalId has already been detached, BadAccess is
+    returned.  The status is always 0.
