Remix mdsprite.c's updateanimation() to look prettier and clearer.

Browse source 
Specifically,
 - rearrange conditionals
 - factor out constant expressions
 - add a couple of debugging printfs for extraordinary events (oob frames)
 - add VERIFY comments for implicit assertions I'd like to verify sometime

Also, one calloc -> malloc.
