Sub display list in TextView TextView uses a sub-display list to 'cache' the rendering of its text. This saves time when drawing an editable text, where the blinking cursor forces a re-draw twice per second, which creates pauses during scrolling. Added a sub-display list invalidation when an appearance span is modified/added/removed. Also added an invalidation of the display list when selection range is changed.
