Sure, it sounds fine to me. We just need to get it spec'd out how the
WM knows to display a bell. i.e. does metacity listen for some Xkb
signal, or do we need to add a client message and support it in
gdk_beep(), or what.
If you want to flash window borders, ideally we could think of a way
to do this in a theme-agnostic fashion (such as lightening the whole
border, or something); otherwise we'll need to break the theme format
to require themes to explicitly define a "flash on" state. The
problem here is knowing which window to flash, though. (Unless you
want to flash them all, but that seems bizarre.)
