+Subject: [PATCH] client: Handle removal of GTK_FRAME_EXTENTS
+
+Chromium and GOOGLE Chrome have now support for GTK_FRAME_EXTENTS.
+
+When maximizing a window, Chromium/Chrome simply removes the property
+on its toplevel rather than setting all values to 0.
+
+xfwm4 would simply ignore the property change because it could not read
+the values and therefore apply the old, wrong values.
+
+Fix xfwm4 to handle the property removal like an actual property change
+to 0.
