[wmx] Full-screen windows?

This is probably a known problem, but in case it isn't, I'd like to
report that full-screen windows don't work very well with (current SVN)
wmx. Here are some examples:

First of all, docks and panels appear above full-screen windows. For
example, running gkrellm (with "Set window type to be a dock or panel"
and "Set sticky state" enabled) and kicker, and then running mplayer in
full-screen mode, mplayer is indeed full-screen but gkrellm and kicker
appear over its window, obscuring its edges.

Other programs don't even turn properly full-screen. For example,
pressing F11 in firefox resizes the window to be full-screen, but it
still has decorations and isn't positioned exactly inside the screen.
Moving it with the mouse seems to fix it, though. Virtualbox exhibits
the same behaviour.

When pressing F11 in eog, the full-screen toolbar appears at the top of
the screen, but the actual image window isn't resized.

Pressing F in xine, the window decorations disappear and the window is
resized to be almost full screen, but not quite - it's a few pixels
smaller.

The only program I found that appears perfectly in full-screen mode is
qiv. Even panels and docks are hidden.

Thanks!
