Subject: dnd/x11: correct coordinates in pos callback
X-Git-Tag: v1.16.0-alpha1~69
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=0363553dfced5eb0a8000c3493bf2fb53407f589;p=platform%2Fupstream%2Felementary.git

dnd/x11: correct coordinates in pos callback

Summary:
The x, y coordinates in pos callback should be relative to
the top-left of the object.
This patch corrects the x,y coordinates and adds poscb to elementary test
to clearly show the bug case.

Test:
      Run Genlist Dnd Dflt Anim with the change in this patch.
      Drag an item to other genlist and see the printed out item, x, y.

@fix
