OpenGL: fixes related to GL_POINTS

I put all usage of GL_POINTS under the microscope. Fixed problems &
optimized a couple of spots.

- reduce calls to glPointSize by about 50%
- draw selected & unselected vertices together for UV editor & EditMesh
- draw initial gpencil stroke point the proper size
- a few other smaller fixes

New policy: each GL_POINTS draw call needs to set its desired point
size. This eliminates half our calls to glPointSize (setting it back to
its 1.0 default after every draw).
