The behavior of the 4x4 matrix method transform_point3() was changed to not
perform the perspective divide. This is an optimization for use with affine
transforms where perspective correction is not required. The
project_point3() method was added for transforming points by perspective
projections.
The 3x3 matrix from_scale() method was changed to
create a affine transform containing a 2-dimensional non-uniform scale to be
consistent with the 4x4 matrix version. The
from_diagonal() method can be used to create a 3x3 scale matrix.
The 3x3 matrix methods transform_point2_as_vec3a,
transform_vector2_as_vec3a and mul_vec3_as_vec3a were unintentionally
pub and are no longer publicly accessible.
Added
Added Vec2::X, Vec4::W etc constants as a shorter versions of unit_x()
and friends.
Added ONE constants for vectors.
Added IDENTITY constants for Mat2, Mat3, Mat4 and Quat.
Added ZERO constant for vectors and matrices.
Added clamp_length(), clamp_length_max(), and clamp_length_min methods
for f32 and f64 vector types.
Added try_normalize() and normalize_or_zero() for all real vector types.
Added from_diagonal() methods to all matrix types for creating diagonal
matrices from a vector.
Added angle_between(), from_rotation_arc() and
from_rotation_arc_colinear() to quaternion types.
Added quaternion inverse() which assumes the quaternion is already
normalized and returns the conjugate.
Added from_translation() and from_angle() methods to 3x3 matrix types.
Added project_point3() method to 4x4 matrics types. This method is for
transforming 3D vectors by perspective projection transforms.
Added Eq and Hash impls for integer vector types.
Changed
Deprecated ::unit_x/y/z(), ::zero(), ::one(), ::identity() functions
in favor of constants.

Breaking Changes
Vec2Mask, Vec3Mask and Vec4Mask have been replaced by BVec2, BVec3,
BVec3A, BVec4 and BVec4A. These types are used by some vector methods
and are not typically referenced directly.
