ItemizedOverlay : margin of error for activate an item

[GoogleCodeExporter]

It could be useful if we can indicate a margin of error for activating items in 
an ItemizedOverlay.

For example, if an item of 12x12 pixels is displayed, it is a little difficult 
to select it. It would be nice if a touch event catched near this item could 
activate it.

Related to issue 141. If icons were scaled according to screen density, this 
would be less of a problem.

Users could then create icons with large enough transparent borders that would 
accommodate a finger press, and the icon would scale properly regardless of 
screen size.

Another approach is to translate the object and the click point to screen 
coordinates and then do a simple distance test. If it is within a configurable 
distance, then it is considered a click. Maybe this should be settable on a 
per-item basis?
