Compositing fun, Alt-key, Trident driver

Hello all.  I recently checked out the Xserver code - it looks very
promising.  Congratulations to everyone involved.  X is finally evolving!

I spent most of yesterday hacking on my window manager (IceWM) and
xcompmgr to play with the translucency and shadow effects.  The main
change I made to xcompmgr is to specify the alpha value in the
CM_TRANSLUCENCY window property (instead of just on or off).  I'm also
considering adding another property (call it CM_SHADOW) to specify what
kind of shadow the window should have, if any.  If anyone else is
interested in these changes, please let me know.

One thing I've noticed is that my right Alt-key has no effect under
Xserver.  It works fine when using the same window manager under XFree86.
All the other keys, including the left Alt-key and both Ctrl-keys work
fine.  Any suggestions as to how to fix this would be most appreciated.

Finally, can anyone tell me what state the Trident driver is in?  The CVS
history suggests that it hasn't been touched in three years, and the build
process does not include it.  My attempts to compile it have met with only
partial success.  I'd like to help get it working if possible.  Are there
any suggestions as to where to get started for one who has no experience
writing graphics drivers?

Thanks for reading.
