[GEM-dev] GLEW and pix_texture

[chris clepper]

I seem to have GEM built with GLEW on Windows however the pix_texture
object was crashing.  It took a little time to trace the crash, but I
finally figured out that it died on GL_APPLE_texture_range.  Now,
let's look at that again in slow-motion: Windows box, Apple specific
extension, crash.  GLEW apparently says 'YES!' to every extension
under the sun, which means we need to clean up some code based on
platform assumptions in order to make it work.
