What features should we add to Corona?

Support iOS touch radius property

Please add support for the touch event properties "majorRadius" and "majorRadiusTolerance" that have been introduced in iOS 8.

These are used to get the size of a touch event, i.e. to discern between a small finger touch, a large finger touch, or a palm that rests on the display.

Unity seems to support this:

Of course, these properties would be nil on Android unless Android adds similar touch properties in the future.
