openbox/openbox/moveresize.c
Dana Jansens b5e597f1b3 lots of fixes for the iconify animation. i think it should all work perfectly now ? 
one change in action.c may affect bindings... THIS COULD BREAK CURRENT CONFIG FILES. ya.
so, if you used a press binding and it moved the window, no enter event will be generated for that anymore because you are holding down the button when the window moves. if you don't like that then use a click binding instead.
