* In general it is not necessary for frames to call this when they change.
* For example, changes that result in a reflow will have this called for
* them by PresContext::DoReflow when the reflow begins. Style changes that
* do not trigger a reflow should have this called for them by
* DoApplyRenderingChangeToTree.
*
* @param aFlags PAINT_COMPOSITE_ONLY : No changes have been made
