Added a fast path for emitting unclipped primitives directly to a
vertex buffer. ELTS are not supported yet (missing functionality in
the DRM). You need at least Savage DRM version 2.1.3, which fixes a
bug that screwed up triangle fans and strips.
Moved the texture normalization stage to savagerender.c.
