Also, isn't page-flipping supposed to be done between front/back buffer of any
DRI drawable, e.g. the one app uses for direct rendering?

However I see that according to DDX and kernel code, current page-flipping code
only supports flipping between displays front and back buffer, and yet DDX uses
it for all page flipping. Isn't that just wrong?

When compiz is runnung apps render to texture and thus DDX should at least for
now failback to blitting for such DRI drawables, no? (although sure it is
possible to implement page-flipping for individual non screen sized DRI
buffers)
