Subject: Added workaround for problem on Mac OS X 10.4.3 where could not share
textures and display lists between a pbuffer and an on-screen OpenGL context;
now specify pbuffer support for all created contexts. Tested on 10.3.9 and
10.4.3. See 4129317 on Apple's Bug Reporter for first report of this bug.
Added workaround for older OpenGL version strings being reported with older
graphics cards on OS X; now attempt to parse vendor-specific version string.
Added workaround for ProceduralTexturePhysics demo on OS X where pbuffer's
rendering results were not being flushed each frame; this demo is now working
properly on 10.4.3 with recent hardware.
