Date: Wed, 22 May 2002 22:30:58 +0300 From: "Mike Gorchak" <mike@malva.com.ua> Subject: One more QNX patch Hi ! - Fixed graywin test application. Added properly support for window size not equal to 640x480. - Added support for not aligned pitch of image in SDL_SWSURFACE and SDL_HWSURFACE. Using Photon builtin alignes. - Added memory clear after each malloc to avoid problems in the future :) - Removed unused variables and static variables, fixed some warnings. - Updated readme.QNX file.
