How to override Window Manager placement of windows.
Is it possible to create a window in X11/WM, but override the position Window Manager sets for the window. I'm not sure how to use 'override_redirect' flag, and what to do in order to use it. But the problem with the flag is also that it probably will disable all decorations given by the WM. Actually I just need to be able to set the windows position programmatically, while the WM puts every window (except popups) at the center of the display. I can only move windows with mouse and it's not the best idea to emulate mouse events to move windows.
