The GLU library is built atop deprecated OpenGL functions, and needs to be purged from Blender's drawing code.

We must complete this task before switching to core profile.

grep -r glu[A-Z] source/blender to find the parts that need to be updated.

We should reimplement gluUnProject, but not the general shape & geometry evaluation library GLU provides. Visit each GLU-using function and determine the best way to perform its task.

TODO:
3D cursor
region_draw_azone_icon
transform manipulator
draw_empty_sphere
draw_empty_cone
draw_bundle_sphere
draw_bb_quadric
draw_bonevert
draw_bonevert_solid
draw_sphere_bone
draw_circle (mask_draw.c)
grease pencil volumetric strokes & dots <-- major recode
