DisplayList properties are still disabled default (flags in View.java and DisplayListRenderer.h). When they are enabled, and when a View has a DisplayList, invalidations due to property changes are now optimized to avoid causing DisplayList recreation. This eliminates the drawing step of invalidation (due to changes in these properties), only requiring issuing the previously-created DisplayList to the GL renderer. Invalidation is slightly faster (less overhead as we walk up the hierarchy), getDisplayList() is potentially much faster (going down to ~0ms), depending on the complexity of the View being redrawn and the size of the invalidated hierarchy.
