This was done to make reviewing easier, again because it is virtually impossible to search for the operators in the code.
Going through this revealed quite a few places where texture animations were on but shouldn't and even more places that did not check PASLVERS, although they were preparing some paletted rendering.
UE1: Add support for Deus Ex format vertex data.
UE1: Group triangles by skin index AND type/flags (preparation for per-surface render style support).
UE1: Add handling of Weapon Triangle (preparation for model attachment support).
UE1: Support flat shaded triangle flag.

This is pretty much 100% functional by now.
Hasn't been tested on platforms other than Linux yet, though.
Code definitely deserves some cleaning.
