In a busy area, zoom in/out takes a long while as items are redrawn.

Maybe not a lot that can be done: better PurgeWays, progressive redrawing (i.e. not a blocking operation), generally try and be lighter on memory usage...

Significantly improved in 0.10d by not redrawing lines if the scale is still the same, and forcing a purgeWays before redraw. Changed to enhancement for future improvements.
