[TextureMapper] Fix preserve-3D intersection rendering
https://bugs.webkit.org/show_bug.cgi?id=282682
Reviewed by Fujii Hironori.
Preserve-3d does not correctly render intersections, and also applying
filters in a 3D scene can break the rendering order. This patch addresses
these issues by implementing the composition and painting logic from the
CSS Transforms Module Level 2.
In a 3D rendering context, rendering and sorting of elements is done as
follows:
1. The element establishing the 3D rendering context, and each other 3D
transformed element participating in the 3D rendering context, is rendered
into its own plane. This plane includes the element’s backgrounds, borders,
other box decorations, content, and descendant elements, excluding any
descendant elements that have their own plane (and their descendants).
This rendering is done according to CSS 2.1,Appendix E, Section E.2 Painting
Order.
2. Intersection is performed between this set of planes, according to
Newell’s algorithm, with the planes transformed by the accumulated 3D
transformation matrix. Coplanar 3D transformed elements are rendered in
painting order.
