This improves, but doesn't fix, the issue with sound popping when the player angle changes.

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.
