title: Linux: resize application window to fit display
body: <p>I have a 1024x768 Qt3 application, and want to run it on a smaller tablet display. Isn't there a way to zoom out the application window, so to fit the display? I mean: not resize widget by widget, but at very low level, frame by frame, as if it were a video. The window should respond to mouse and keyboard, obviously.
  Thank you!
