window: Handle TOUCH_BEGIN events separately during grab ops

Browse Source 
Handle the case of a TOUCH_BEGIN event during window dragging separately
instead of treating it like a TOUCH_UPDATE event: Simply return TRUE to
make Clutter stop event propagation if it's the pointer emulating
sequence and let Clutter propagate the event if it isn't.
