- From manual it is quite unclear what are needed to do double buffering
- in overlay framebuffer. In examples provided in 4Dgifts only one
- buffer mode is used. Yet in manual page mswapbuffers() and in
- other places it sounds like that double buffer mode in overlay is
- about the same as normal buffer.
-
- Does anyone has experience in programming in double buffer mode in
- overlay framebuffer? What is needed?
-
- We have a GTX, with 4 bit overplay plane.

- Thanks,
