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.
