Made FAST_FLOOR_DIV work correctly, replaced all floorf() divisions with it.

Still not perfect - chunk and region calculations can be made into a single CPU instruction - SAR - but not all compilers are known to support that (">>" operator on signed datatypes needs to perform arithmetic shift, C/C++ standard makes it implementation-specific; MSVC and GCC do what we need, LLVM unknown)
