*
* CONFIGURATION:
*
* #define RAYMATH_IMPLEMENTATION
* Generates the implementation of the library into the included file.
* If not defined, the library is in header only mode and can be included in other headers
* or source files without problems. But only ONE file should hold the implementation.
*
* #define RAYMATH_STATIC_INLINE
* Define static inline functions code, so #include header suffices for use.
* This may use up lots of memory.
