Replace GL_FLOAT

Use 'unsigned int[3]' array for total color

Merge branch 'blender2.8' into greasepencil-object

Cleanup: Avoid redundant/accidental struct copying

Cleanup: move BKE_pbvh_vertex_iter_end into same scope as BKE_pbvh_vertex_iter_begin

It turns out this worked, but still reads awkwardly.

Cleanup: variable names, const correctness, formatting

This makes the code match more closely with BKE_mesh conventions.

Also remove unused WPaintDefer struct.

Cleanup: move WPaintData, VPaintData, WeightPaintInfo back into paint_vertex.c

There is no reason to make these public
Revert allocated ViewContext, its no longer needed.

Cleanup: headers

Cleanup: remove redundant headers-in-headers

This brings the branch closer to master.

Also remove unused 'indexar' & 'accumulate_stack'.

Cleanup: move inline ViewContext out of vpaint structs

This required a bunch of indirect includes,
change this for neater includes and a single allocation here isn't causing performance problems.
