  Says who? That's like saying that whatever texturing elements are used,
they ABSOLUTELY MUST apply to any element of any scene. Clearly UV-mapping
doesn't do this, yet nobody is complaining.

  I see no problem in triangle meshes supporting lightmaps, and these
lightmaps being pre-calculated using the algorithm called "radiosity".
(In fact, lightmaps are not very far from UV-mapping. It's just an
additional layer on top of the texture layer.)

  And why, exactly? I see no technical, ideological nor philosophical
problem with it.
