Additional debug code is included for visualizing the state of the vsp data structure.
Further, fix issue in drawpoly where it would access out of bounds of dpxy if fewer than 3 vertices were passed in and fix issue where multiple calls to polymost_setVisibility() were repeatedly setting the visibility factor to the same value.

Additionally, raise minimum number of stencil buffer bits to accomodate future use of the stencil buffer.

Polymost visibility: compensate for the classic mode "truncating" the lookup shades by moving the fog ramp by the equivalent of 1/2 shade
Fix some issues with negative shade in GL fog.

It's garbage and the "functionality" it provided is something that will be able to be achieved in a better way in a future commit.

This codebase doesn't work on any platforms where int64_t isn't even a type.

This was necessary because everything is already allocated with the Xmalloc() functions, but a future commit will make blocks allocated with those functions no longer compatible with the system implementation of free(), which Bfree() wraps.

Some of the variable initialization ordering may look counterintuitive at first, but it's intended to avoid read-after-write memory access penalties.

This doesn't so much fix the issue as band-aid over it--it appears to be an OG BUILD bug that has happened since long before I ever began improving the clipping, I don't know what causes it, and I don't want to fuck everything up trying to fix it right now.

This may also fix a minor performance regression introduced in Polymer sometime after we switched to building as C++, caused by confusion between STRUCT_TRACKERS_ENABLED and UNTRACKED_STRUCTS. UNTRACKED_STRUCTS is now named UNTRACT_STRUCTS__ to dissuade use outside of buildtypes.h.

Due to less branching, this is actually faster than trying to be clever.

Doing this as cleanly as possible involved demoting several function parameters concerning object sizes and counts from size_t to int--I'm fine with this change as the functions in question are not actually capable of handling input with sizes larger than what can be stored in a signed 32-bit integer, making the use of size_t here misleading at best.
