MX (Multiple conteXt) support was dropped from the GLEW 2.0 library to make core profile support cleaner.
Our WITH_GLEW_MX build option was OFF by default already; this commit removes the inactive code paths.
I'm working on a plan for multiple GPUs, contexts, resource sharing, etc. This commit gives us a cleaner starting point for that upcoming work.
Tested on Mac, will test on Linux & Windows immediately after pushing.
This is an auto-generated list, crossing gl-deprecated.h, glew.h and the
Blender code. It allows Blender to build with core profile.
WITH_OPENGL_LEGACY=ON: nothing changes
WITH_OPENGL_LEGACY=OFF and WITH_GL_PROFILE_CORE=OFF:
It stubs deprecated legacy calls.
WITH_OPENGL_LEGACY=OFF and WITH_GL_PROFILE_CORE=ON:
It stubs deprecated legacy calls thus allowing Blender to build with
core profile only.
Technically you only want to use WITH_OPENGL_LEGACY=OFF when
WITH_GL_PROFILE_CORE=ON. But it doesn't hurt to have it working for both
scenarios.
