Window Decoration Workarounds

[Jonathan B. Horen]

 From the Xfce FAQ:

"6. Why are there no options to start an application without any window 
decoration, to "keep it on top" of other windows, or to make it disappear 
from the taskbar ?

xfwm4 does not, and will never, include any mechanism to bypass what the 
application wants. The application should allow this by using standard hints 
for Window Managers. Moreover, by doing it in the application, it will work 
with all WM. Gkrellm2 is a good example of such implementation."

OK, fair's fair.  So, does anyone know of a replacement for "xclock" (which, 
sadly, doesn't know about window-manager resources)?
