[Bf-committers] FSAA and Blender

[Ton Roosendaal]

Hi,

I remember we tried to fix errors reported with FSAA and Blender, but  
disabling GL_MULTISAMPLE_ARB didn't work... it seems drivers prefer to  
enforce this onto programs that were coded without FSAA in mind.

There are no recent checks/reports on this though.
