Summary0000003: Implement TA vertex compiler
DescriptionCurrent TA implementation is very Q+D, although it works with most apps that don't touch the poly lists/tile maps directly. There's a test case failure with the KOS render speed test though, caused by the fact that the test expects the compiled vertex list to be smaller than it is at the moment.

We need to
1. Determine (and document) the mapping from TA objects to compiled poly objects
2. Implement this in the the TA code
3. Rewrite the renderer to work from the compiled objects rather than the TA lists.

While this is not in itself a high priority, it will need to be done eventually for accuracy and currently blocks a lot of other renderer work that would otherwise need to be rewritten when the renderer is changed as here.

Also note that this would also clean up the current bg-plane hack (which uses a compiled poly structure)

There's a few outstanding compliance issues, but functionally looks to be at least on par with the previous implementation (plus correctly parsing everything now).

Memory management looks to be 100% now. Outstanding feature issues:
* Tile clip
* Re-initialize mode

Outstanding (known) bug-compliance issues:
* Polygon header in the middle of a vertex list (breaks horribly)
* Vertexes outside of a list context (looks like modifier list processing)
* Certain combinations of flags that raise a "bad input" exception.

Tile clip implemented (not fully bug-compatible yet)
Unable to get the "reinit" register to do anything useful - postponing until I have a working example.

Closing this bug and raising the bug-compatibility issues as a separate (much lower priority) bug.
