From: "Mike Gorchak"
Subject: Patches for tests and QNX6
Here more fixes for the QNX6 in sdlqnx.diff file:
- Spellchecked README.QNX (thanks to Julian Kinraid)
- Fixed bugs in fullscreen mode: window region wasn't on top by default, so \
it caused some artifacts to be appeared on the screen, prevent window conten\
ts default filler in Photon while in fullscreen mode, it damages the screen.
- Added support for the SDL_VIDEO_WINDOW_POS, SDL_VIDEO_CENTERED env variabl\
es.
- Some minor code restructurization.
