Modified sprite management so that if in the course of processing its

dirty rectangles, an animated view has to expand the dirty region, it can
call back to the sprite manager to determine whether this new, expanded
dirty region includes sprites that weren't previously considered to be
dirty. If so, those sprites' rendered bounds are added to the dirty
rectangle list being processed so that they will be properly redrawn
(which may trigger more sprites to be included and so on).

Also modified sprite internals in a cleany uppy sort of way.
