[Bug 967267] [NEW] Position delta attributes incorrect when touch count changes

[Launchpad Bug Tracker]

You have been subscribed to a public bug by Vibhav Pant (vibhavp):

Some gestures continue when the number of touches changes. When this
happens, much of the gesture state is reset. This includes the original
center and cumulative transformation matrix.

Geis currently stores the last position coordinates and uses them to
calculate the delta for the next event. When the touch count changes and
the grail gesture state is reset, the geis calculation often results in
wildly incorrect values.
