-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;
