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.

longer provide access to their underlying image (they actually still do,
but not in the normal course of affairs). This will allow us to use
"trimmed" tiles which are trimmed to the smallest rectangle that contains
the non-transparent pixels in a tile image, which will shrink up our
components and other tiles a great deal.

things compile and most things run so this is a good time to checkpoint.
Let me recall:
- Refactored the whole scene deal.
- Revamped the XML parser stuff (now uses Digester).
- Rethought the tile management.
- Started tile bundle stuff.
- Wrote some tests.
- Did a bit of Mike-ification.
Onward and moreward.

will now obtain tile set information directly from the tile sets.

Made TileSet an interface. Throw exceptions for unknown tile or tile
set requests. General clean-up and documentation.

interface. Initial version of AStarPathUtil and hooked it in to
SceneView.getPath(). Not yet tested.

distance parameters to tile sets. Removed constant tile width/height
references except, for now, for isometric tile rendering which still
requires tiles that are 32x16.

to separate scene display from editing functionality. Load and
initialize managers in a fashion that more appropriately hides the
implementation details. Tidied comments up a bit.

rendering the tiles from an isometric perspective. Added comments and
minor clean-up.
git-svn-id: svn+ssh://src.earth.threerings.net/narya/trunk@88 542714f4-19e9-0310-aa3c-eee0fc999fb1
Modified TileManager to store the height of a tile in the Tile
object's member data when the tile is initially created since we
would like to be able to reference it speedily.
git-svn-id: svn+ssh://src.earth.threerings.net/narya/trunk@63 542714f4-19e9-0310-aa3c-eee0fc999fb1
config information from miso.properties for now. Don't pass around
ImageObservers since we're hoping to be able to address that
differently.
