- added conversion macros to convert floating point angles to angle_t, using xs_Float.h, and replaced all occurences in the code with them (let's hope I found everything.)

Converting a floating point value that is out of range for a signed integer will result in 0x80000000 with SSE math, which is used exclusively for this purpose on modern Visual C++ compilers, so this cannot be used anywhere.
On ARM there's problems with float to unsigned int conversions.

xs_Float does not depend on these
