Introducing an immediate mode drawing API that works with modern GL 3.2 core profile. I wrote and tested this using a core context on Mac. This is part of the Gawain library which is Apache 2 licensed. Be very careful not to pull other Blender code into these files. Modifications for the Blender integration: - prefix filenames to match rest of Blender’s GPU libs - include GPU_glew.h instead of <OpenGL/gl3.h> - disable thread-local vars until we figure out how best to do this
