Don't color by texture in `IndexedLookup` mode.

Using a texture map to color geometry assumes
that interpolation can be performed (although
this can be disabled with `GL_NEAREST`)  and
that scalar values are numeric. This need not
be true in indexed lookup mode as annotations
may be string- or variant-valued.
