preparation for character component compositing and other
character-related antics.

that they can assign a new path to the sprite should they choose to do
so.

gather dirty sprites and objects and render after base and fringe tile
layers. Add shadow tiles in the footprint of objects to make them
impassable.

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.

that observers can do things like remove sprites without unhappy
side-effects.

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.

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

implementing them with the miso stuff.
