Sets surface as the icon for a given drag. GTK+ retains
references for the arguments, and will release them when
they are no longer needed.
To position the surface relative to the mouse, use
cairo.surface.Surface.setDeviceOffset on surface. The mouse
cursor will be positioned at the (0,0) coordinate of the
surface.
