Changeset 1273 in josm

Message:

We don't need to transform each node to check it for visibility. So for each visitAll(), transform the current screen bounds coordinates to EastNorth only once and do each visibility check of an OsmPrimitive against these values.

Put getColors() back in, was a merge mistake ;-)
