Summary: 3rd parameter for Tkinter.scan_dragto

Initial Comment:
In Tk8.3 (possibly earlier), one can add a third
optional parameter, called "gain", which determines the
multiplier used when performing the panning operation.
 The Tkinter call does not allow this parameter to be
passed in the resultant Tk's default gain of 10 is
often unusable.

Work around is to just do this call manually:

    self.canv.tk.call(self.canv._w, 'scan', 'dragto',
event.x, event.y, 1)

uses a gain of `1'.
