Description
### Use case
The user wants to scale with a single pointer. This is a common gesture where the user performs a double tap, but on the second tap, instead of lifting the pointer they begin panning. The axis with the largest delta wrt the location of the second tap determines the scale. This is used in Google Earth (a Flutter app), Google photos and FireFox mobile, as well as many other apps.
### Proposal
Add a new gesture recognizer called double tap and pan gesture recognizer that recognizes this gesture and add it to GestureRecognizer.
