We now have a separate resize button. The rotate button just rotates. The resize button scaled with fixed aspect ratio by default, or freely with CTRL. It's trivial to change it so it resizes freely by default (or to change the access key) if we want. svn path=/trunk/KDE/kdebase/workspace/libs/plasma/; revision=757843
