Optimizing DisplayList properties
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.
