The idea I am writing at all is that for typical settings current centering 
strategy was odd. Encountered linux, win32. I can see macosx is affected too.

Resize is not an option in general, especially for screens with ~768 pixels
height giving you ~700 pixels. If it was, KDialog's size hint would do the job.

Example: I am displaying a print preview as a floating window (non-modal dialog)
that is by default as large as availableGeometry() of course, as user expects 
to see
as much details on the preview by default (resizing the height to ~400 pixels 
the preview - 9 of 10 users would need to resize the window by hand).

I am talking about default kicker-on-bottom settings. See the attached 
first.gif mockup.
Perhaps a variation of the idea could be even better: do the centering using 
screenGeometry() horizontally and using availableGeometry() vertically, see 
second.gif. This gives us correct behaviour for kicker-on-the-left/right-hand 
setting too.
