There is more than one problem.  Here are two of them:

1. Using enable-disable of GL_COLOR_MATERIAL does not properly disable the
state.  I confirmed this using just OpenGL calls, on multiple NVidia cards
and drivers.  I also found a workaround, which consists of calling
glColorMaterial(GL_FRONT, GL_DIFFUSE) *before* calling
glEnable(GL_COLOR_MATERIAL ) for the first time.  No logical reason why this
should make it work, but it does.

2. I haven't found a way to use ssgSimpleState/ssgVtxTable to make simple
colored geometry.  That's the current killer, if there's no solution then
i'll have to abandon PLIB/SSG.

Thanks,
Ben
