/* From the docs about minimumTouchPoints/maximumTouchPoints:
"...allow you to, for example, have nested MultiPointTouchAreas,
one handling two finger touches, and another handling three finger touches."
But in this test they are side-by-side: the left one handles any number
of touches up to 2, and the right one requires 3.
