Fix Intel issues on the OpenGL renderer

GoogleCodeExporter commented 9 years ago

failures are likely due to unexpected differences between NVIDIA and Intel 
drivers.

Document but don't try to work around driver bugs.

Fixes MipMapTest on Intel/OpenGL.

Add a flush before looping to get the sync status.

Intel GPUs enter an infinite loop unless told to flush.
