From: Mike Gorchak <mike@malva.ua>
Subject: New QNX patches
- Added more error check to avoid SEGFAULTS;
- Fixed bug in update function for SDL_HWSURFACE. BTW: update is much
faster than before.
- Added checks for SDL_HWSURFACE flag, chosen bpp must be equal to
desktop bpp for SDL_HWSURFACE.
- Fixed overlay bug, no more SEGFAULTS.
