This change enable automatic cropping using -1 set to left, top, right or bottom property. In the case both side are set to automatic cropping, the croping will be done equally on both side (in the odd case, right and bottom cropping will be 1 pixel more). https://bugzilla.gnome.org/show_bug.cgi?id=687761
