-*
-* raymath v1.5 - Math functions to work with Vector2, Vector3, Matrix and Quaternions
-*
-* CONVENTIONS:
-* - Matrix structure is defined as row-major (memory layout) but parameters naming AND all
-* math operations performed by the library consider the structure as it was column-major
-* It is like transposed versions of the matrices are used for all the maths
-* It benefits some functions making them cache-friendly and also avoids matrix
-* transpositions sometimes required by OpenGL
-* Example: In memory order, row0 is [m0 m4 m8 m12] but in semantic math row0 is [m0 m1 m2 m3]
-* - Functions are always self-contained, no function use another raymath function inside,
-* required code is directly re-implemented inside
-* - Functions input parameters are always received by value (2 unavoidable exceptions)
-* - Functions use always a "result" variable for return
-* - Functions are always defined inline
-* - Angles are always in radians (DEG2RAD/RAD2DEG macros provided for convenience)
-* - No compound literals used to make sure libray is compatible with C++
-*
-* 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.
