get latest OpenGL version on Windows + AMD
When we ask for GL 3.2 compatibility profile:
AMD (Radeon HD 6970) gives us exactly this version
NVIDIA (Quadro K600) gives at least this version
Still need to check Intel behavior
We want *at least* the version requested, plus more recent features if
available.
Both GPUs tested & mentioned above are capable of GL 4.5. With this
commit they both give 4.5 to Blender.
