KWin's current interpretation of "maximized" is "geometry exactly matches

If a window's maximum size is smaller than the size of the workarea, then
indeed the window cannot be resized to be maximized. And, even if KWin tried
to resize the window to its maximum size in such case, you'd still have no
guarantee it'd place it where you want.

Kicker, besides being a dock window (KWin::setType() + NET:ock), also does
or doesn't set its strut (KWin::setStrut()) which makes it reserve a certain
area at some screen edge. KWin sees struts of all windows and makes workarea
to be the screen area minus place takes by struts.

Since this has to do with managing windows, I guess it should be done in the
window manager, hence the name. Since I assume that toolbar you're talking
about is just a normal torn-off toolbar of some application, this should even
be the Kicker case, and you're probably talking about
http://bugs.kde.org/show_bug.cgi?id=26425 . If implemented, KWin could have
an option to automatically snap a torn-off toolbar of the active application
to some edge and it'd work for all apps, not inconsistently just yours.
If you'd be willing to give it a try, just say so and I'll give you some
hints. It would be a bit more complicated than just putting a call to
resize() at some point but it should be limited to the parts of KWin which
are no rocket science.
