From: "Mike Gorchak"
Subject: SDL/QNX6 new patch

Here in attachment my patch for the SDL/QNX6 again :) It contain non-crtitical/cosmetic fixes:

1. Fixed window centering at other than the first consoles.
2. Fixed window centering algorithm in case when window height or width are greater than the desktop resolution.
3. Fixed window positioning on other than the first consoles.
4. Fixed occasional input focus lost when switching to fullscreen.
5. Removed the Photon's default chroma color for the overlays, added RGB(12, 6, 12) color instead (very dark pink).
6. Added more checks to the YUV overlay code (fixed crashes during resolution mode switches).
7. Added support for Enter/Backspace keys in unicode mode (used by Maelstrom and by other games).
8. Fixed window restore/maximize function. It works, finally.

Environment variables:

Please note that the photon driver is sensible to the following
environmental variables:

* SDL_VIDEO_WINDOW_POS - can be set in the "X,Y" format. If X and Y
coordinates are bigger than the current desktop resolution, then win-
dow positioning across virtual consoles is activated. If X and Y are
smaller than the desktop resolution then window positioning in the
current console is activated. The word "center" can be used instead of
coordinates, it produces the same behavior as SDL_VIDEO_CENTERED
environmental variable.

* SDL_VIDEO_CENTERED - if this environmental variable exists then the
window centering is perfomed in the current virtual console.

The SDL_VIDEO_CENTERED enviromental variable has greater priority
than the SDL_VIDEO_WINDOW_POS in case if both variables are supplied
to the application.
