Keep the rendering result in an OpenGL texture and use it for repaint during reflow;
stop using double tree algorithm for repaint and reflow to simplify the tree manipulation.

r2934 ‐ Introduce Canvas class for offline rendering using ARB_framebuffer_object OpenGL extension
r2935 ‐ Keep the rendering result in the canvas of each Window object

r2976 ‐ Do not reflow an absolutely positioned box if the size of the content area is same
r2990 ‐ Support partial reflow of inline blocks and floating boxes
r3065 - Process collapse-through margins during incremental reflow

✓ TODO: Incremental selector matching and block box reconstruction

When elements are added or removed to a DOM tree, selector matching should be executed only for a part of the DOM tree.
