Skipping handling of properties for override redirect windows has two advantages: first it reduces the amount of work needed to get an override-redirect window (menu, tooltip, drag icon) onto the screen. But more importantly, it reduces the number of code-paths for an override-redirect to get into some code portion where it isn't expected. * Integrate the list of properties we load initially with the list of property hooks; this avoids having two separate lists that we have to keep in sync. * Add a flag to MetaWindowPropHooks to indicate whether the property should be handled for override-redirect windows; currently we load a) properties that identify the window - useful for debugging purposes b) WM_TRANSIENT_FOR (could be used to associate menus with toplevels.) * For properties that aren't always loaded through window-props.c, add !window->override checks to places that trigger loading, and add g_return_if_fail(!window->override) to the load functions as a double-check. http://bugzilla.gnome.org/show_bug.cgi?id=582639
