st/vega: Move vertex transformation to shader.
It was done in path-to-polygon conversion. That meant that the
results were invalidated when the transformation was modified, and CPU
had to recreate the vertex buffer with new vertices. It could be a
performance hit for apps that animate.

st/vega: Fix paint coordinates transformations.
Depending on whether vgDrawPath(mode), vgDrawImage, or vgDrawGlyph[s] is
called, different paint-to-user and user-to-surface matrices should be
used to derive the sample points for the paint.
This fixes "paint" demo.

st/vega: Add color transformation support.
Per OpenVG 1.1. A new shader stage is added. It uses the first two
constants of the fragment shader for color transformation parameters.
