The display list is an immutable data structure, so once it's created, rasterization can be moved to a separate thread. This allows more room for performing other tasks between processing HTML rendering tasks. This change makes PaintingSurface, ImmutableBitmap, and GlyphRun atomic ref-counted, as they are shared between the main and rendering threads by being included in the display list.
