If at least one finger has moved at least 10 mm, a zoom event is considered. If the distance between the fingers has
changed by at least 10 mm, and both fingers have stayed on approximately the same line, Zoom Mode is entered. If
either finger strays more than 10 mm from the "zoom line" created when the fingers first made contact, the zoom is
canceled.
To zoom out, place two fingers on the item you want to reduce (one finger quickly followed by the second), then move
them towards each other.
Rotate Gesture
To change the orientation of an object on the screen, place two fingers on the image you want to rotate (one finger
quickly followed by the second), then move them in opposite directions (as if you were turning a knob). The direction
the item turns is dependant upon the direction you move your fingers.
If at least one finger moves at least 12 mm, a rotate is considered. If one finger is stationary (moving less than 5 mm
in any direction), and the other is moving, a rotate is considered. If the fingers begin moving in the same direction,
the rotation is canceled. If the distance between the fingers changes by more than 10 mm, the rotation is canceled.
