simple line path calculations that don't suffer from the accumulated
rounding errors that our previous method did.

directions, otherwise movement in one direction will unnecessarily reset
the "move stamp" for the other direction in which we didn't actually move.

follow a path (specifically, I want to allow the media panel to be
"scrolled" along a path).

same math that the scrolling code does to scroll in a straight line.

the notion of velocity and they can expose that interface to whomever
creates them. We don't need to set the velocity in the abstract.

that is generated by cutting up a small image into nine sections and using
each appropriately to create the expanded background.

internal images and doesn't necessarily need to decode them into multiple
images or even have actual images at all. This cleans things up and paves
the way for our "trimmed" image support which is forthcoming.

animations currently operating therein. (It doesn't pause scrolling which
I suppose I'll have to fix at some point if we ever need it.)

sprite was following a path is going to scroll; fixed bug in
getDirection(); added setDuration() which computes the path velocity based
on the time that the sprite should spend following the path.

animation images. Created and made use of basic single- and
multi-image implementations of the MultiFrameImage interface.

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.

implementing them with the miso stuff.

conversion routines for fine and full coordinates, and moved
iso-related utility functions to IsoUtil.
