SqMod/source/Entity/Sprite.cpp
Sandu Liviu Catalin b818a162ee Initial implementation of the standard math library.
Implemented utilities to convert between fundamental types.
Implemented helper functions to retrieve numeric values from the stack at all costs.
Implemented various delegates on the long integer types to mimic the standard types.
Moved most of the stack utilities in a separate source.
Various other fixes and improvements.
