half/half. I was nervous to remove per-vertex coloring completely, for fear that it would be needed somewhere. It can still be sent and used by the renderer if necessary. The current gles renderer does not enable the color attrib, so it should be a no-op.

My reasoning for not removing it from the frag shader is that i believe some of the video renderers may be using it. But you're right, for gles, we should probably be able to nuke it completely.
