From: "Mike Gorchak"
Subject: Batch of the QNX6 fixes for the SDL
1. Updated readme.QNX
2. Fixed crashes during intensive window updating under fast machines (got over 200 rectangles for update).
3. Fixed double-buffered fullscreen modes, now it works as needed.
4. Fixed Photon detection algorithm.
5. Fixed HWSURFACE update function.
6. Added SDL_PHOTON_FULLSCREEN_REFRESH environment variable support for control refresh rates under Photon.
7. Added 640x400 fullscreen mode emulation via 640x480 (if videodriver not supports original 640x400 mode of course) shifted by 40 vertical pixels from begin, to center it. It's needed for some old DOS games which ran in doubled 320x200 mode.
8. Added available video ram amount support.
8. Added hardware surface allocation/deallocation support if current videomode and videodriver supports it.
9. Added hardware filling support.
10. Added hardware blits support (simple and colorkeyed).
And I've added to testvidinfo test color-keyed blits benchmark (maybe need to add alpha blits benchmark too ?). Currently Photon not supporting any alpha hardware blittings (all drivers lack of alpha blitting code support, only software alpha blitting exist in photon, which is hundreds times slowest than the SDL's one). So I've not added the alpha support. I suppose new QNX 6.3 will have the hardware alpha support, so when it will be done, I'll add alpha support.
