I'd like Transforms to have some QoL methods (examples will follow), and would like to hear what the sentiment towards that would be (I know we want to be careful with implementing too many new features).

Here is my wishlist (much of these are influenced by Unity's Transforms:

• Transform::forward() -> Vec3 Get the normalized direction pointing towards in model-space
• Transform::look_at(&mut self, &Vec3) Rotate the Transform, so that it looks at a certain position
• General methods to rotate the Transform e.g. around a certain axis, or orbit around a certain point. Those could be better kept as constructors for Quat, though.
• Transform::face_towards(&mut self, ..) -> Self same as Transform::new(Mat4::face_towards(..)) but minimizes the amount of Mat4s the average user has to deal with
• Transform::apply(&mut self, other: &Transform) transform your transform by another transform ;)
• I'm sure more will come to mind later

The mutable methods would also only be implemented on Transform but not on GlobalTransform (although refining the difference between Global- and Transform could be another Issue).

If everyone's on board I'd like to use this issue to collect wanted features for Transforms and open a pull request to implement them.
