servo: Merge #6214 - First step towards 3d transforms (from glennw:parse-transforms); r=pcwalton
* Add parser support for 3d transforms. * Change ComputedMatrix to a representation that suits interpolation. * Switch stacking contexts to use 4x4 matrices. The transforms themselves are still converted to 2d and handled by azure for now, but this is a small standalone part that can be landed now to make it easier to review. Source-Repo: https://github.com/servo/servo Source-Revision: 05212b702dbafacd3d1d44e600139af8d7516308
