31 * The painting of a layer occurs in three distinct phases. Each phase involves
32 * a recursive descent into the layer's render objects. The first phase is the background phase.
33 * The backgrounds and borders of all blocks are painted. Inlines are not painted at all.
34 * Floats must paint above block backgrounds but entirely below inline content that can overlap them.
35 * In the foreground phase, all inlines are fully painted. Inline replaced elements will get all
36 * three phases invoked on them during this phase.
