Summary: Colours have no effect on textured geometry

Initial Comment:
Diffuse/Transparency colours have no effect on textured geometry.

The QuickDraw3D behaviour is to modulate colors on geometry 
using a null shader, otherwise it is ignored. Quesa should probably 
support this behaviour as the default, but allow Phong/Lambert lit 
geometry to modulate colours via an extended API.

Some testing with the GeomTest app shows that TriGrid and Triangle 
geometries actually do respect vertex colours when textured.

Although blending works on those geometries, the behaviour is 
backwards to that of QD3D (geometry lit Phong/Lambert blend colours, 
null shader does not). This seems to be intended looking at the 
ir_texture_set_state function however.
