  HandmadeMath.h v2.0.0

  This is a single header file with a bunch of useful types and functions for
  games and graphics. Consider it a lightweight alternative to GLM that works
  both C and C++.

  =============================================================================

  CONFIG

  By default, all angles in Handmade Math are specified in radians. However, it
  can be configured to use degrees or turns instead. Use one of the following
  defines to specify the default unit for angles:

    #define HANDMADE_MATH_USE_RADIANS
    #define HANDMADE_MATH_USE_DEGREES
    #define HANDMADE_MATH_USE_TURNS

  Regardless of the default angle, you can use the following functions to
  specify an angle in a particular unit:

    HMM_AngleRad(radians)
    HMM_AngleDeg(degrees)
    HMM_AngleTurn(turns)

  -----------------------------------------------------------------------------

  Handmade Math ships with SSE (SIMD) implementations of several common
  operations. To disable the use of SSE intrinsics, you must
  define HANDMADE_MATH_NO_SSE before including this file:

    #define HANDMADE_MATH_NO_SSE
    #include "HandmadeMath.h"

  -----------------------------------------------------------------------------

  To use Handmade Math without the C runtime library, you must provide your own
  implementations of basic math functions. Otherwise, HandmadeMath.h will use
  the runtime library implementation of these functions.

  Define HANDMADE_MATH_PROVIDE_MATH_FUNCTIONS and provide your own
  implementations of HMM_SINF, HMM_COSF, HMM_TANF, HMM_ACOSF, and HMM_SQRTF
  before including HandmadeMath.h, like so:

    #define HANDMADE_MATH_PROVIDE_MATH_FUNCTIONS
    #define HMM_SINF MySinF
    #define HMM_COSF MyCosF
    #define HMM_TANF MyTanF
    #define HMM_ACOSF MyACosF
    #define HMM_SQRTF MySqrtF
    #include "HandmadeMath.h"
  
  By default, it is assumed that your math functions take radians. To use
  different units, you must define HMM_ANGLE_USER_TO_INTERNAL and
  HMM_ANGLE_INTERNAL_TO_USER. For example, if you want to use degrees in your
  code but your math functions use turns:

    #define HMM_ANGLE_USER_TO_INTERNAL(a) ((a)*HMM_DegToTurn)
    #define HMM_ANGLE_INTERNAL_TO_USER(a) ((a)*HMM_TurnToDeg)

//
// Note that as mentioned at the top of the paper, the paper assumes the matrix
// would be *post*-multiplied to a vector to rotate it, meaning the matrix is
// the transpose of what we're dealing with. But, because our matrices are
// stored in column-major order, the indices *appear* to match the paper.
//
// For example, m12 in the paper is row 1, column 2. We need to transpose it to
// row 2, column 1. But, because the column comes first when referencing
// elements, it looks like M.Elements[1][2].
//
// Don't be confused! Or if you must be confused, at least trust this
// comment. :)
