[dependabot]

Updates the requirements on glam to permit the latest version.

Changelog

Sourced from glam's changelog.

[0.17.1] - 2021-06-29

Added

• Added serde support for Affine2, DAffine2, Affine3A and DAffine3.

[0.17.0] - 2021-06-26

Breaking changes

• The addition of Add and Sub implementations of scalar values for vector types may create ambiguities with existing calls to add and sub.
• Removed From<Mat3> implementation for Mat2 and From<DMat3> for DMat2. These have been replaced by Mat2::from_mat3() and DMat2::from_mat3().
• Removed From<Mat4> implementation for Mat3 and From<DMat4> for DMat3. These have been replaced by Mat3::from_mat4() and DMat3::from_mat4().
• Removed deprecated from_slice_unaligned(), write_to_slice_unaligned(), from_rotation_mat4 and from_rotation_ypr() methods.

Added

• Added col_mut() method which returns a mutable reference to a matrix column to all matrix types.
• Added AddAssign, MulAssign and SubAssign implementations for all matrix types.
• Added Add and Sub implementations of scalar values for vector types.
• Added more glam_assert! checks and documented methods where they are used.
• Added vector projection and rejection methods project_onto(), project_onto_normalized(), reject_from() and reject_from_normalized().
• Added Mat2::from_mat3(), DMat2::from_mat3(), Mat3::from_mat4(), DMat3::from_mat4() which create a smaller matrix from a larger one, discarding a final row and column of the input matrix.
• Added Mat3::from_mat2(), DMat3::from_mat2(), Mat4::from_mat3() and DMat4::from_mat3() which create an affine transform from a smaller linear transform matrix.

Changed

• Don't support AsRef and AsMut on SPIR-V targets. Also removed SPIR-V support for some methods that used as_ref(), including hash(). Not a breaking change as these methods would not have worked anyway.

Fixed

• Fixed compile time alignment checks failing on i686 targets.

[0.16.0] - 2021-06-06
