/*
HandmadeMath.h v1.13.0
This is a single header file with a bunch of useful functions for game and
graphics math operations.
=============================================================================
To disable SSE intrinsics, you MUST
#define HANDMADE_MATH_NO_SSE
in EXACTLY one C or C++ file that includes this header, BEFORE the
include, like this:
#define HANDMADE_MATH_NO_SSE
#include "HandmadeMath.h"
=============================================================================
If you would prefer not to use the HMM_ prefix on function names, you can
#define HMM_PREFIX
To use a custom prefix instead, you can
#define HMM_PREFIX(name) YOUR_PREFIX_##name
=============================================================================
To use HandmadeMath without the CRT, you MUST
#define HMM_SINF MySinF
#define HMM_COSF MyCosF
#define HMM_TANF MyTanF
#define HMM_SQRTF MySqrtF
#define HMM_EXPF MyExpF
#define HMM_LOGF MyLogF
#define HMM_ACOSF MyACosF
#define HMM_ATANF MyATanF
#define HMM_ATAN2F MYATan2F
Provide your own implementations of SinF, CosF, TanF, ACosF, ATanF, ATan2F,
ExpF, and LogF in EXACTLY one C or C++ file that includes this header,
BEFORE the include, like this:
#define HMM_SINF MySinF
#define HMM_COSF MyCosF
#define HMM_TANF MyTanF
#define HMM_SQRTF MySqrtF
#define HMM_EXPF MyExpF
#define HMM_LOGF MyLogF
#define HMM_ACOSF MyACosF
#define HMM_ATANF MyATanF
#define HMM_ATAN2F MyATan2F
#include "HandmadeMath.h"
If you do not define all of these, HandmadeMath.h will use the
versions of these functions that are provided by the CRT.

//
// 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. :)
