Date: Sat, 23 Mar 2002 13:53:37 +0200 From: "Mike Gorchak" <mike@malva.ua> Subject: Big QNX patch again. Added 8bit palette emulation code for window mode with bpp>=15. Added store/restore original palette for 8bit modes. Added more information about photon API call fails. Rewroten change palette code, slow but works. Fixed bug with set caption before window was inited. Fixed bugs with some initial state of variables. Fixed bug with storing old video mode settings. Fixed bug with switching to fullscreen mode and back. Fixed few double SEGFAULTS during parachute mode. Removed compilation warning with no PgWaitHWIdle prototype. Removed pack of dead unusable code. Cleanups SDL_PrivateVideoData structure, some headers. Some code formatting.
