This patch change resizing behavior of kwin. This behavior is used in Fvwm and Ctwm window managers. It is a little complex to explain, but, I'll try. Currently, when you resize a window, you press meta key, you click on window and window is resizing. With this patch, window isn't resizing until pointer go out of window. This allows a quick and precize resizing. Try it.
I work on 3.4.3 version of kdebase from experimental packages of Debian (deb http://ftp.de.debian.org/debian ../project/experimental main). I know, I should work on svn trunk. This patch is small, and you shouldn't have problems to use it with other versions.
If you like this resize style, vote for its (better) integration in svn trunk of kwin (Bugs #105946 of http://bugs.kde.org).
