Summary

CSS 3D Transforms extends CSS Transforms to allow elements rendered by CSS to be transformed in three-dimensional space.

Create 2D elements that can be moved and animated in 3D space (could be used to create interesting 3D UI elements).

Automated test cases:
- Reftests in layout/reftests/transform-3d
- CSS property tests are in layout/style/test (mainly test_transitions_per_property.html)
- layout/base/tests/test_preserve3d_sorting_hit_testing.html

505115 - CSS3 3D-Transforms
604899 - poor text rendering with dancing characters at html5test.com
676746 - layersGPUAccelerated flags appears to be incorrect for the windows test machines.
689498 - Intersecting planes are not z-ordered properly
689504 - Reflow + thebesLayer content repaint happening all the time while rendering morphing cubes
689760 - Falling leaves are very slow, re-allocating textures on each paint...
695964 - "ASSERTION: Can't get a delta for an untransformed frame!" with transform, svg:foreignObject
696936 - "ASSERTION: Perspective must be positive!" (quirks mode only)
699360 - "ASSERTION: Our frame tree is likely to be bogus!" with transition, "transform-style: preserve-3d"

All test cases were run on the Firefox version the feature is targeted for (Firefox 10.0).
All the major bugs have been fixed.
