DrawTargets that support region clipping are able to clip to regions effectively. Other DrawTargets go through expensive complex clip paths. When invalidating regions we have code that draws in multiple steps when using Direct2D to avoid this expense, we should base the decision to do this simply on whether the DrawTarget supports fast region clipping.
