Date: Thu, 12 Mar 2009 15:14:38 +0200 From: "Mike Gorchak" Subject: New QNX patches In photon.tar.gz there are new files to be placed into ./src/video/photon/ directory. qnx3.diff - new patches for QNX support. Since I've found a lot of bugs in the new GF QNX Graphics Framework and I'm suspended development for GF driver until already found bugs will be fixed and switched to Photon driver implementation. sdl.diff - I've found that renderer creation result has not been checked and SDL shows error like: "there is no current renderer", now SDL will show correct error which was set be renderer.
