- Adding new function ChopWindingInPlaceAccu() in polylib.c. This function is
just like ChopWindingInPlace() except that the winding input has the higher
vect_accu_t resolution. I actually did a deep massage of this code as well
(went over it with a fine-toothed comb). I still need to examine it at least
one more time when I'm fresh, and fix an issue related to choosing the value
for maxpts.
- In mathlib.h, defining VEC_SMALLEST_EPSILON and VEC_ACCU_SMALLEST_EPSILON
constants that will help determine suitable epsilons to use for certain
operations. Comments are provided detailing what these constants do.
- In mathlib.h, defining DotProductAccu() and VectorCopyAccu().
- Small comment in brush.c that has concerns about a certain use of
BaseWindingForPlane() in WriteBSPBrushMap().
State of this code is: compiles on Linux. May not compile on Windows. Not
tested (new functionality not used yet in any real code, only functions exist).

- Adding new function BaseWindingForPlaneAccu() in polylib.c. Analogous to
original BaseWindingForPlane() only that the return value is a
winding_accu_t (new type w/ double precision). This function is not being
used yet.
- Restoring the original BaseWindingForPlane() function (pre-r371). Will keep
this as a reference. What I did exactly:
* Renamed BaseWindingForPlane() to BaseWindingForPlaneAccu(), changed stuff.
* Renamed _BaseWindingForPlane_orig_() to BaseWindingForPlane(), preserved.
- Adding things like vec_accu_t, vec3_accu_t, VectorSubtractAccu(),
VectorAddAccu(), VectorScaleAccu(), CrossProductAccu(), and
winding_accu_t. Also AllocWindingAccu() and FreeWindingAccu().
- Removing the recently added VectorSetLength() function because it is no
longer needed.
State of this code is: compiles, not tested (new functionality not used yet).
