Abuse SVECTOR padding field to store the normal index, so we don't need to do an extra lookup inside the draw loop.

Made some sense of entity-local transformations, though performing scaling and translation of the vertex data is proving to be a problem.

First genuine result: combined view and projection matrices allow camera controls in Quake coordinate system with aspect ratio correction.

Small optimization: instead of branching, we can do UV correction with a single calculation.

Cleaned up some things and made some fixes to allow the app to run on real hardware again.
Turns out setting the padding to 0 on SVECTORS is quite necessary, to avoid getting into undefined behavior territory.

Added converted Shambler model.
Performance is now starting to take a hit when displaying both models at the same time, so GTE acceleration is becoming necessary.
