* rewrote ColorControl.h
* removed unused stuff. * shuffled methods around in the source, so that you don't have to jump so far when working at a specific thing (ie. all draw functions are grouped together, ...) * ResizeToPreferred() should now work as expected. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@14934 a95241bf-73f2-0310-859d-f6bbb57e9c96
