Revert "Port UV display to new design. As plus, we can remove the extra buffer completely"

This reverts commit a5e3c4f04ce0b36ed78c88a221ccca5a3d2bcd50.

I was too hasty in concluding this could be removed easily

Port UV display to new design. As plus, we can remove the extra buffer completely

Port texture paint and mcolor GPU upload to new design

Textured and GLSL drawing for cddm except from tangent layer
now ported correctly to new display paradigm

Merge branch 'master' into temp-derivedmesh-looptri

Conflicts:
source/blender/blenkernel/intern/cdderivedmesh.c

Start move drawing code for cdderivedmesh to indexed/mpoly design.
This is WIP mostly to merge some work that gets rid of code we
don't really need to port.

No need to use looptri to convert vertex colors

Use mloopcol to check if we want to enable colors for drawing

Merge branch 'master' into temp-derivedmesh-looptri

match looptri axis calculation with editmesh & tessface

correct for mistake

Fix for DM_draw_attrib_vertex which was temp disabled

Correct bad index use

Re-Branch temp-derivedmesh-looptri against master
