3.0.0 (2023-06-07)
 * Added Rect4*.h and Box6*.h for 2D and 3D boundaries, with numeric types matching those provided by Vector*

 * Added Scalar.h
 * Added IntegerFraction
 * Added Grid
 * Added MoveInput
 * Added ActionInput
 * Adopted Armature, Animation (now ArmatureAnimation), AnimationState (now ArmaturePose), Camera, OrbitCamera, WalkCamera, and TextureAtlas from renderer. TextureAtlas is somewhat simplified from its previous form, containing only a mapping between hash table keys and rectangles and some basic math for transforming them to pixel dimensions.
 * Added Vector*_invert() and Vector*_inverted()
 * Added Vector*_multiplyComponents() and Vector*_divideComponents()
 * Added Vector*_toBarycenter() and Vector*_fromBarycenter() (replacing now-removed Barycentric.h)

 * Added Vector2*_rotate90CW(), Vector2*_rotate90CCW(), and Vector3*_perpendicular()
 * Added Vector3*_rotate[XYZ]90CW, Vector3*_rotate[XYZ]90CCW(), and Vector3*_rotate[XYZ]180()
 * Added Vector*_positionOnLine(), Vector[34]*_positionOnPlane(), and Vector3*_closestLinePointToLine()
 * Added Vector*_round()
 * Added Rect/Box*_getSize(), Rect/Box*_constrainWithin(), Rect/Box*_intersectionNonempty(), Rect/Box*_unionNonempty(), and Rect/Box*_clampVector*()
 * Added Quaternion*_magnitude(), Quaternion*_magnitudeSquared(), Quaternion*_isZero(), and Quaternion*_isEqual()
 * Added Matrix4x4*_isEqual() and Matrix4x4*_isIdentity()
 * Added a context pointer to Interpolation to allow it to be used with ParameterSpline and other things that require extra data
 * Added matrix functions for constructing a transformation without immediately multiplying by it, and a convenience leftMultiply() function.
 * Added calculator executable target
 * Renamed Quaternion to Quaternionf, and added Quaternionx for fixed point calculations
 * Renamed Matrix to Matrix4x4f, and added Matrix4x4x for fixed point calculations
 * Fixed multiplications in Vector*x_reflect() and Vector*x_magnitude() giving wildly incorrect results
 * Fixed a bug that caused xsqrt to be nonterminating for some inputs
 * xmul and xdiv now return FIXED_16_16_INF or FIXED_16_16_NINF if the result overflows a 32-bit type
 * xmul and xdiv now return FIXED_16_16_INF, FIXED_16_16_NINF, or FIXED_16_16_NAN as appropriate if one of both of their inputs is inf or nan
 * Renamed interpolationContext's "interval" field to "duration"

2.2.0 (2014-11-02)
 * Renamed project from 3dmath to gamemath to more accurately fit its purpose
 * Added Interpolation module
 * Added xtof, ftox, xtod, and dtox macros (aliases of fixed16_16ToFloat, floatToFixed16_16, fixed16_16ToDouble, and doubleToFixed16_16, respectively)

2.1.1 (2014-06-29)
 * Added support for modern Xcode/iOS SDK versions
 * Renamed Matrix_rotate() "angle" parameter to "radians" for clarity

2.1.0 (2014-01-22)
 * Added Vector*_project()
 * Added Vector*_distance() and Vector*_distanceSquared() (2.0.0 had prototypes for them but implementations were missing)
 * Added Vector2x_rotate()
 * Vector*_reflect() is now implemented correctly to return reflection rather than negated reflection
 * Removed Vector_legacy.h
 * Fixed-point multiply and divide now round the result instead of truncating

2.0.0 (2014-01-10)
 * Added FixedPoint
 * Vector2, Vector3, and Vector4 now come in f (float), d (double), i (int), and x (16.16 fixed-point) variants
 * Legacy code can #include "3dmath/Vector_legacy.h" for macros that make existing references to Vector2, Vector3, and Vector4 behave as Vector2f, Vector3f, and Vector4f, respectively
 * Replaced Vector*_init() functions with VECTOR*(x, y[, z[, w]]) macros (type suffix is lower case)
 * Replaced Quaternion_init() function with QUATERNION(x, y, z, w) macro
 * Replaced Matrix_init() function with MATRIX(...) macro
 * Removed unfinished and unused Frustum

1.4.0 (2013-07-08)
 * Vector*_normalize() now returns a success boolean. Zero-magnitude vectors now return false and remain unaltered.
 * Added Matrix_interpolate() and Matrix_interpolated()
 * Added Vector*_scaleTo() and Vector*_scaledTo()
 * Added Vector2 and Vector4 constants: VECTOR2_LEFT, VECTOR2_RIGHT, VECTOR2_DOWN, VECTOR2_UP, VECTOR4_LEFT, VECTOR4_RIGHT, VECTOR4_DOWN, VECTOR4_UP, VECTOR4_BACK, VECTOR4_FRONT, VECTOR4_KATA, and VECTOR4_ANA
 * Added 64-bit Windows and Linux support

1.3.0 (2012-04-10)

1.2.0 (2011-10-13)
 * Added Vector2_rotate() function
