-Enough people asked, so here's my test program which reparents another
-window. It's a single file (reparent.c), and will work with Motif or
-Xaw. Xaw users should comment out the "#define MOTIF" line.
-
-The reparent program first prompts for the application name of the
-client that it will reparent. If you're going to start the
-application override_redirect (e.g. -xrm "*overrideRedirect: true"),
-then this name is ignored and the first override_redirect window is
-assumed to be the one.
-
-Input focus is supposed to be correctly handled, as is resizing with
-window manager hints. If you have input focus problems, try launching
-your application override_redirect instead. This method is preferred
-anyway, since you can map it off-screen and then avoid the "window
-flash" effect as the application's top-level window is reparented.
