// DESCRIPTION:
// Lookup tables.
// Do not try to look them up :-).
// In the order of appearance:
//
// int finetangent[4096] - Tangens LUT.
// Should work with BAM fairly well (12 of 16bit,
// effectively, by shifting).
//
// int finesine[10240] - Sine lookup.
// Guess what, serves as cosine, too.
// Remarkable thing is, how to use BAMs with this?
//
// int tantoangle[2049] - ArcTan LUT,
// maps tan(angle) to angle fast. Gotta search.
//
