commit b48348e7726878fa78e161a7f0c2fb530d7b1fca
Author: Matthias Clasen <mclasen redhat com>

gdk: Allow passing the start coordinates in drag_begin
Add a variant of gdk_drag_begin that takes the start position
in addition to the device. All backend implementation have been
updated to accept (and ignore) the new arguments.
Subsequent commits will make use of the data in some backends.
