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.
