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