[9fans] 9vx: ...and if you love plan9 more than your x86 host

[Abhishek Kulkarni]

It's more fun to use 9vx in the fullscreen mode to get a complete
Plan9 experience.

Press <F11> to toggle fullscreen mode.
Patch attached.

Thanks for 9vx. It makes things a lot easier :)

Checked F11 code into hg.  Instead of sending the window
manager a "make me fullscreen" request like your code did,
the code I added (taken from p9p) just resizes the window
to take up the whole screen.  I would be happy to use the
window manager version (which I added, but if'ed out)
except that it doesn't work with p9p rio.  Please speak up if
the "move the window" approach doesn't work with your
window manager.  If it doesn't, then we can make your
version the default once someone volunteers to add support
to rio.
