Use the node and leaf data to traverse the entire BSP tree and draw all attached faces.
This already gets rid of all the collision volumes that were being drawn before.

Added a more aggressive inlining macro. Not sure if it makes any difference now, but it's nice to have the option.

Split face drawing off into a separate function, and made triangle fan and triangle strip available again as alternative options, for comparison.
Also using triangle fan as a special case for faces with three vertices, i.e. a simple single triangle.

Implemented quad strip topology for rendering faces, which is actually a good bit simpler than triangle strips.

Faces can now carry their own per-vertex lighting data, instead of sharing all vertex data with adjacent faces.

Faces now have a vertex index list, which is more space-efficient and allows easy rewrites of polygon topology.
Also works quite well with the scratchpad RAM setup.

Rewrote scratchpad function to work more as I envisioned it:
sequential calls will pass on a variable to each other that gets updated with the new offset position in the scratch buffer.

First simple test with scratch memory, just to verify that it works.

Set up some helper functions for memory management, including scratchpad memory. Moved the primitive buffer here too.
This will probably have to become inline functions or macros at some point, but for now it's just pure C.

Modified triangle rendering code so that it finally works on real hardware.
Not sure why the original method doesn't work, probably some weird limitation on the memory/GTE register subsystems.
This will get rewritten anyway so it doesn't matter much now.

First implementation of world loading and rendering. No BSP logic or optimizations in here yet, but something is being displayed!
