Step one in migrating to use glArray calls in Blender

- Curve/Nurbs/Font/MBall now all draw arrays.
- had to flip abgr to rgba in shaded drawing
- Mesh drawing can't be easily done; the indices for faces are not in
  in one chunk. Also need a way to gether trias/quads, per material.

Speedup results are mixed. Something between 2-4 times. Especially for
text it seems to help.
