Version	Changes
1.4.0	Fixed bug when using C mode. SSE'd all vec4 operations. Removed zeroing for better performance.
1.3.0	Removed need to `#define HANDMADE_MATH_CPP_MODE`. C++ definitions are now included automatically in C++ environments.
1.2.0	Added equality functions for `HMM_Vec2`, `HMM_Vec3`, and `HMM_Vec4`, and SSE'd `HMM_MultiplyMat4` and `HMM_Transpose`.
1.1.5	Added `Width` and `Height` to `HMM_Vec2`, and made it so you can supply your own `SqrtF`.
1.1.4	Fixed SSE being included on platforms that don't support it, and fixed divide-by-zero errors when normalizing zero vectors.
1.1.3	Fixed compile error in C mode
1.1.2	Fixed invalid HMMDEF's in the function definitions
1.1.1	Resolved compiler warnings on gcc and g++
1.1	Quaternions!
1.0	Lots of testing
0.7	Added HMM_Vec2, and HMM_Vec4 versions of HMM_LengthSquared, HMM_Length, and HMM_Normalize.
0.6	Made HMM_Power faster, Fixed possible efficiency problem with HMM_Normalize, RENAMED HMM_LengthSquareRoot to HMM_LengthSquared, RENAMED HMM_RSqrtF to HMM_RSquareRootF, RENAMED HMM_SqrtF to HMM_SquareRootF, REMOVED Inner function (user should use Dot now), REMOVED HMM_FastInverseSquareRoot function declaration
0.5.2	Fixed SSE code in HMM_SqrtF and HMM_RSqrtF
0.5.1	Fixed HMM_Translate producing row-major matrices, ensured column-major order for matrices throughout
0.5	Added scalar operations on vectors and matrices, added += and -= for hmm_mat4, reconciled headers and implementations, tidied up in general
0.4	Added SSE Optimized HMM_SqrtF, HMM_RSqrtF, Removed use of C Runtime
0.3	Added +=,-=, *=, /= for hmm_vec2, hmm_vec3, hmm_vec4
0.2b	Disabled warning C4201 on MSVC, Added 64bit percision on HMM_PI
0.2a	Prefixed Macros
0.2	Updated Documentation, Fixed C Compliance, Prefixed all functions, and added better operator overloading
0.1	Initial Version
