another reason i am avoiding textures for the moment is that i will
need to update that pie-wedge piece of the texture every 5 ms. or so.
given my current understanding if the opengl api, it would be easier
to update the colors of part of a vbo (or of an entire vbo if i split
the vbo up into 400 pieces).

thanks
