2590 mac intel and radeon pro 5300m horrible fps 2 (#3030)

* OpenGL 3.3 compatibility pass.  Fix for FBO driven downscaling corrupting textures.
* Increase maximum texture bias, immediately scale down when textures are loaded higher resolution than desired
* #2590 Fix for some frame stalls on Intel Macs
