/**

 * This class provides sticky header functionality in a list view, to use with

 * SetupWizardIllustration. To use this, add a header tagged with "sticky", or a header tagged with

 * "stickyContainer" and one of its child tagged as "sticky". The sticky container will be drawn

 * when the sticky element hits the top of the view.

 *

 * There are a few things to note:

 * 1. The two supported scenarios are StickyHeaderListView -> Header (stickyContainer) -> sticky,

 *    and StickyHeaderListView -> Header (sticky). The arrow (->) represents parent/child

 *    relationship and must be immediate child.

 * 2. The view does not work well with padding. b/16190933

 * 3. If fitsSystemWindows is true, then this will offset the sticking position by the height of

 *    the system decorations at the top of the screen.
