+Support for doublebuffer hardare
+
+This code is designed to support doublebuffer hardware where the
+displayed buffer is selected on a per-pixel basis by an additional bit
+plane, called the select plane. It could probably be easily modified
+to work with systems that use window-id planes.
+
+This is done by creating a new drawable type, DRAWABLE_BUFFER. The
+type has the same exact layout as a window drawable. Your code should
+treat a DRAWABLE_BUFFER the same as it would tread a DRAWABLE_WINDOW
+when handling the gc drawing functions. In addition, PaintWindowBackground,
+CopyWindow, and all of the gc drawing functions to be able to draw into both
+framebuffers. Which framebuffer to draw into is selected by the contents of
+	pWin->devPrivates[frameWindowPrivateIndex].
+The content of the devPrivate is either from frameBuffer[0] or
+frameBuffer[1], depending on which buffer is being drawn into. When
+	pWin->devPrivates[frameWindowPrivateIndex] == frameBuffer[0],
+the functions should draw into the front framebuffer. When
+	pWin->devPrivates[frameWindowPrivateIndex] == frameBuffer[1],
+the functions should draw into the back framebuffer.
+
+In addition, you need to provide a function that allows you to copy
+bits between the buffers (optional since CopyArea can be used) and a
+function that draws into the select plane. Then, you need to register
+your functions and other information, by calling:
+
+void
+RegisterDoubleBufferHardware(pScreen, nInfo, pInfo, frameBuffer, selectPlane,
+			     CopyBufferBitsFunc, DrawSelectPlaneFunc)
+    int			nInfo;
+    xMbufBufferInfo	*pInfo;
+    DevUnion		*frameBuffer;
+    DevUnion		selectPlane;
+
+"pInfo" is an array indicating which visuals and depths that double
+buffering is supported on. "nInfo" is the length of the array.
+
+"frameBuffer" is array of length 2. The contents of the array element
+is ddx-specific. The content of frameBuffer[0] should, when placed in
+the window private, indicate that framebuffer 0 should be drawn into.
+The contents of frameBuffer[1], when placed into the window private,
+should indicate that framebuffer 1 should be drawn into.
+
+"selectPlane" is ddx-specific. It should contain information
+neccessary for your displayProc to access the select plane.
+It is passed to DrawSelectPlaneFunc.
+
+"CopyBufferBitsFunc" is a ddx-specific function that copies from one
+buffer of a multibuffered window to another buffer. If the CopyBufferBitsFunc
+is NULL, a default function will be used that calls pScreen->CopyArea.
+
+    void CopyBufferBitsFunc(pMBWindow, srcBufferNum, dstBufferNum)
+        mbufWindowPtr pMBWindow;
+        int srcBufferNum, dstBufferNum;
+
+"DrawSelectPlaneFunc" is a ddx-specific function that fills the
+regions "prgn" of select plane with the value "bufferNum". If 
+selectPlane is a DrawablePtr (such as a PixmapPtr), you can pass
+NULL for DrawSelectPlaneFunc, a default function will be used that
+calls FillRectangle on the selectPlane.
+
+    void DrawSelectPlaneFunc(pScreen, selectPlane, prgn, bufferNum)
+        ScreenPtr	pScreen;
+        DevUnion	selectPlane;
+        RegionPtr	prgn;

+ * BIGFONT extension for sharing font metrics between clients (if possible)
+ * and for transmitting font metrics to clients in a compressed form.
+ *
+ * Copyright (c) 1999-2000  Bruno Haible
+ * Copyright (c) 1999-2000  The XFree86 Project, Inc.
+ */
+
+/* THIS IS NOT AN X CONSORTIUM STANDARD */
+
+/*
+ * Big fonts suffer from the following: All clients that have opened a
+ * font can access the complete glyph metrics array (the XFontStruct member
+ * `per_char') directly, without going through a macro. Moreover these
+ * glyph metrics are ink metrics, i.e. are not redundant even for a
+ * fixed-width font. For a Unicode font, the size of this array is 768 KB.
+ *
+ * Problems: 1. It eats a lot of memory in each client. 2. All this glyph
+ * metrics data is piped through the socket when the font is opened.
+ *
+ * This extension addresses these two problems for local clients, by using
+ * shared memory. It also addresses the second problem for non-local clients,
+ * by compressing the data before transmit by a factor of nearly 6.
+ *
+ * If you use this extension, your OS ought to nicely support shared memory.
+ * This means: Shared memory should be swappable to the swap, and the limits
+ * should be high enough (SHMMNI at least 64, SHMMAX at least 768 KB,
+ * SHMALL at least 48 MB). It is a plus if your OS allows shmat() calls
+ * on segments that have already been marked "removed", because it permits
+ * these segments to be cleaned up by the OS if the X server is killed with
+ * signal SIGKILL.
+ *
+ * This extension is transparently exploited by Xlib (functions XQueryFont,
+ * XLoadQueryFont).

+There are several code fragments that need to be placed in the device
+dependent part of the server.  These are described below.  These code
+fragments are device and implementation dependent.
+
+This code fragment should go in your ddx InitInput() routine:
+
+#ifdef XTESTEXT1
+extern KeyCode xtest_command_key;
+#endif
+
+#ifdef XTESTEXT1
+    xtest_command_key = <whatever-is-a-good-keycode-for-your-keyboard>;
+#endif
+
+This code fragment should go at the front of the file that handles
+keyboards:
+
+#ifdef XTESTEXT1
+/*
+ * defined in xtestext1di.c
+ */
+extern int	on_steal_input;
+extern Bool	XTestStealKeyData();
+#endif XTESTEXT1
+
+This code fragment should go in the function that parses input from the
+keyboard or pointer after you know what input action has occurred, but before
+you have told the server about it.  If conditionalizes the actual function
+call to pass the information on:
+
+#ifdef XTESTEXT1
+	if (!on_steal_input ||
+	    XTestStealKeyData(code, direction, dev_type, x, y))
+#endif /* XTESTEXT1 */
+	handle_device_event(...);
+
+This code fragment should go in the function that handles mouse motion after
+you have figured out how much the mouse has moved:
+
+#ifdef XTESTEXT1
+	if (on_steal_input)
+	    XTestStealMotionData(dx, dy, dev, x, y);
+#endif XTESTEXT1
+
+
+This code fragment should go at the front of the os-specific code where
+you wait (by doing a select on the socket in our implementation) for
+something to happen:
+
+#ifdef	XTESTEXT1
+extern int	playback_on;
+void XTestComputeWaitTime();
+#endif  XTESTEXT1
+
+These code fragments should go in the os-specific code on both sides of
+where you wait (by doing a select on the socket in our implementation)
+for something to happen:
+
+#ifdef XTESTEXT1
+	    if (playback_on)
+		    XTestComputeWaitTime(wt = &waittime);
+#endif XTESTEXT1
+	    ... code to do select ...
+	    WakeupHandler(i, LastSelectMask);
+#ifdef XTESTEXT1
+	    if (playback_on)
+		    i = XTestProcessInputAction(i, &waittime);
+#endif XTESTEXT1
+
+
+You also need to implement the following routines (documentation
+is needed; for now, see server/ddx/hp/hp/x_hil.c):
+
+void
+XTestGenerateEvent(dev_type, keycode, keystate, mousex, mousey)
+	int	dev_type;
+	int	keycode;
+	int	keystate;
+	int	mousex;
+	int	mousey;
+
+void
+XTestGetPointerPos(fmousex, fmousey)
+	short *fmousex, *fmousey;
+
+void
+XTestJumpPointer(jx, jy, dev_type)
+	int	jx;
+	int	jy;
+	int	dev_type;

+** File: 
+**
+**   xvmain.c --- Xv server extension main device independent module.
+**   
+** Author: 
+**
+**   David Carver (Digital Workstation Engineering/Project Athena)
+**
+** Revisions:
+**
+**   04.09.91 Carver
+**     - change: stop video always generates an event even when video
+**       wasn't active
+**
+**   29.08.91 Carver
+**     - change: unrealizing windows no longer preempts video
+**
+**   11.06.91 Carver
+**     - changed SetPortControl to SetPortAttribute
+**     - changed GetPortControl to GetPortAttribute
+**     - changed QueryBestSize
+**
+**   28.05.91 Carver
+**     - fixed Put and Get requests to not preempt operations to same drawable
+**
+**   15.05.91 Carver
+**     - version 2.0 upgrade
+**
+**   19.03.91 Carver
+**     - fixed Put and Get requests to honor grabbed ports.
+**     - fixed Video requests to update di structure with new drawable, and
+**       client after calling ddx.
+**
+**   24.01.91 Carver
+**     - version 1.4 upgrade
+**       
+** Notes:
+**
+**   Port structures reference client structures in a two different
+**   ways: when grabs, or video is active.  Each reference is encoded
+**   as fake client resources and thus when the client is goes away so
+**   does the reference (it is zeroed).  No other action is taken, so
+**   video doesn't necessarily stop.  It probably will as a result of
+**   other resources going away, but if a client starts video using
+**   none of its own resources, then the video will continue to play
+**   after the client disappears.
