I don't really like the idea of translucent buttons. They're either so transparent that they will accidentally get pressed when someone tries to pan to that location, or they're so opaque that they end up stealing screen space anyway. I'll see what I can do, though.

The problem here is that the map moves while you're panning, so while you're drawing the circle, the map is moving with your stylus, which would not only confuse ordinary users but make it difficult to accurately draw your circle around the area into which you're trying to zoom.

I'm not willing to sacrifice drag-panning for the sake of circle-zooming.
