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.

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.
