Android tap location doesn't match visual location

I've done several fake dialogs. The trick is to group the dialog with a a 
semi-transparent full screen graphic layered behind the dialog group. 
Greying the screen is normal behavior on Android and works on iOS too. The 
graphic has blocker mouse handlers so clicking it does nothing. That way 
you can script the dialog buttons to respond themselves. The user needs to 
click one of the buttons to make the dialog go away, at which point you 
hide the group.

The buttons can put the response in the dialogData, which is a built in 
mechanism to transfer custom messages to a script, or else you can put the 
response in a global or a custom property.
