pass an entire entity to the shader unit. fix a bug in cliptriangle.

an entity is passed instead of a model so we can access
its frame of reference to perform the model-to-world
transformation.

the bug in cliptriangle was due to sd[01] being declared
as static which, when rendering multiple entities, was
causing d0 = d1, which led to division-by-zero.
