/**
* The customize mode transition has 4 phases when entering:
* 1) Pre-customization mode
* This is the starting phase of the browser.
* 2) LWT swapping
* This is where we swap some of the lightweight theme styles in order
* to make them work in customize mode. We set/unset a customization-
* lwtheme attribute iff we're using a lightweight theme.
* 3) customize-entering
* This phase is a transition, optimized for smoothness.
* 4) customize-entered
* After the transition completes, this phase draws all of the
* expensive detail that isn't necessary during the second phase.
*
* Exiting customization mode has a similar set of phases, but in reverse
* order - customize-entered, customize-exiting, remove LWT swapping,
* pre-customization mode.
*
* When in the customize-entering, customize-entered, or customize-exiting
* phases, there is a "customizing" attribute set on the main-window to simplify
* excluding certain styles while in any phase of customize mode.
