WARNING: REVIEWED: Follow a set of conventions

CONVENTIONS:
  - 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
  - Functions use always a "result" variable for return
  - Functions are always defined inline
  - Angles are always in radians (DEG2RAD/RAD2DEG macros provided for convenience)
