non-transparent pixels in an image.

to handle scrolling in a much cleaner and happier way. There's now a
VirtualMediaPanel which operates in virtual coordinates and can be made to
"view" any location in those virtual coordinates. By changing the view,
the view can be scrolled and the view can be made to center on a pathable
(generally a sprite) which will cause it to scroll around as the pathable
moves around in the virtual coordinate space.

of rectangle objects. Thus rendering hundreds of tiles each frame has an
"undesirable" impact on garbage collection. I think Walter and I were
seeing something like 400k per second of garbage. So we're back to
extracting a subimage, which we're pretty sure doesn't copy the image
data, but simply draws the cropped image data directly from the original
rasters without creating shitloads of garbage.

(useful when the path is actually operating in virtual coordinates which
are mapped to scrolled view coordinates by the pathable).

rounding errors that our previous method did.

peacable continued frame painting in cases where a component gets in a bad
way and fails to paint itself happily.

the "move stamp" for the other direction in which we didn't actually move.

"scrolled" along a path).
