Ben Visness efd9f2f4b7 Matrix Multiply SSE (#65) 
* SSEd HMM_MultiplyMat4 and HMM_Transpose. And added HMM_LinearCombineSSE

* Maybe Travis doesn't support SSE?

* Fix compile process so the SSE option is consistently defined

* Fix link error

* Documentation

* Added function prototype for operator ==

* Added != operator for hmm_vec2, hmm_vec3, hmm_vec4

* Add C versions of equality checks

Also made the C++ tests actually run...😳

* Update documentation

Version Changes
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
