Make it easier to start actions depending on the number and type of pointers

Expected behavior

Hello :) I want, that a draggable needs either one mouse event or two touch events to be draggable. The event passed by the draggable move handler doesn’t seem to have a variable “touches”, or any other way to differentiate between touch and mouse. Is there a way to solve that? The reason: On mobile one finger should be free to scroll around the page, and two finger should trigger the movement. Similar to the google maps plugin.

It should be possible to disable dragging when only one pointer is down so that the page can be panned with a single finger, and start dragging if 2 fingers go down together.

Actual behavior

Only gesturable actions can have two pointers.
