Sometimes it can be useful to skew UI elements to do a "flip" animation. These would still be 2D transforms since everything uses 2D matrices, but 3d effects can be emulated using a simple skew. This would mess with assumptions of transforms being affine, so the impacts of that will have to be considered.
