 Is it really necessary to have something so special like flags for 
splashscreens and fulscreen windows? I mean, what makes these two so special 
that they deserve their own flags? Splashscreen is just a window without 
decorations centered on the desktop above all other windows, and fullscreen 
is a window without decorations large as the desktop above all other windows.

 I don't know why neither Matthias Ettrich nor Bradley T. Hughes said 
anything, they are probably busy with Qt3.0 final. KDE already has NET_WM 
extensions that allow both splashscreens and fullscreen windows using more 
generic flags (which is IMHO a better solution). The two flags are 
NET_WM_STATE_STAYS_ON_TOP (it's not even marked as KDE extension in the docs, 
but I can't find it in the wm-spec) and _KDE_NET_WM_WINDOW_TYPE_OVERRIDE. The 
first one is obvious, and some users set this flags e.g. on ICQ window. The 
override flag is almost like using override_redirect, i.e. no decorations, 
but it has the benefit of e.g. staying only on the given desktop.

 Splashscreen is then an override window with staysontop, with geometry set 
by the app (centered and some sane size). Fullscreen windows are override 
windows with size set to desktop size.

 WRT being able to put other windows above a fullscreen one, it would be 
nice, but I see a little problem here : The fullscreen window should be above 
dock type windows (panel), and dock type windows should be above normal 
windows, so normal windows apparently can't go above the fullscreen window. 
Right now KDE/Qt makes fullscreen windows also staysontop.
