render when not showing). Also leave the animation manager running until
it is explicitly shut down.

larger item but still rely on the dirty item to know how to paint
itself.

rather than codes to indicate different types of events. Also modified
name of sprite observer callback as spriteChanged() implies that the
sprite actually changed which it may not have, whereas handleEvent()
doesn't imply anything other than the sprite observer is being asked to
deal with a sprite event.

Modified sprite and path code to make use of these timestamps to determine
a sprite's progress along the path. Abstracted the path stuff so that
paths other than line segment paths can be cleanly implemented.

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.

necessary means by which to invalidate and paint. Now the SceneViewPanel
rather than the SceneView is what the animation manager talks to. It then
passes the necessary information on to the SceneView.

them.
Modified sprite manager to invalidate the view when sprites are added and
removed.
