OpenGL Refactor: Main Task

In this tasks we list all TODOs and sub-tasks for the 2.8 OpenGL refactor.

#49043 (replace OpenGL immediate mode in Blender 2.8)
#49042 (remove GLU from Blender 2.8)
#49012 (update OpenGL requirements for Blender 2.8)
Move to completely shader based drawing (wiki page )
Replace deprecated OpenGL matrix stacks with custom transform functions (wiki page )
Use OpenGL vertex attributes to simplify DerivedMesh drawing (wiki page )
~~remove OpenGL display lists~~
remove DrawPixels (2D raster version)

Apple has a good short article about transitioning to GL core profile. Briefly covers the major changes needed.

Hi, I'm new here and trying to become a useful (hopefully longterm) contributor to Blender. This sounds like an awful task to start out on but at the same time matrix math is super up my alley. Any suggestions on how I might be useful here? #49043 is something I have experience with and seems like a pretty localized task.

Hey @pdlla, we can always use some help ;) I wouldn't recommend starting with the matrix stack replacement which should be written by someone who's more familiar with Blender's drawing code (and who's familiar with future plans). It's more a design challenge, the math is already there. #49043 is indeed a better task to start with.

@pdlla with the recent updates on #49043 we're set up better for contributions now.
