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[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.
