Alrighty Then!

Doing another viewer for a 200+ maps project, i discovered that combining overview and detail maps in the same view, rendered the system unusable with only a few layers.

Naturally i did some optimizations on the layer drawing code. This resulted in a dramatical performance improvement when combining large overview maps with detail maps in the same view.

No more performance penalty. Why not show all of your data at once.

Please see the multi-layer demo showing ~140 maps (Oct 31st, 2008).

Every layers visibility and alpha can be controlled. Arrange depth order with drag and drop.
