constructed. The reason being that derived classes want to override things
like updateRenderOrigin() which should be called every time the sprite's
location is set, but if we do it in the base class constructor, a derived
class's updateRenderOrigin() will be called before the derived class's
constructor has been called. This is not good. Neither was the existing
code which simply half-assed a location change by updating the sprite's
origin position but not calling updateRenderOrigin(), leaving things
generally confuzzled.

We don't want to do that when we mean simply to repaint the whole
component.

definitely not going to be a valid value.

reasons: we don't want anything coming in between the call to tick() and
the call to paint() and components will likely want to be validated before
they are ticked if they happen to be a frame participant and are invalid.

of the origin offset so that it's an offset rather than a negative offset.

pathable except that the pathable is not tracked with the center of the
screen but instead their bounds are kept inside the visible area.

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.

are mapped to scrolled view coordinates by the pathable).
