[compiz] Window hints and options

[Mike Dransfield]

Looking through the code for the plugins, it seems
like there is a need to apply options to individual
windows and window types.

As far as I can see there are 2 basic needs for the
plugin developer.

1. Run time tagging of windows similar to XHints.
I do not think plugin developers should resort to
xlib coding for this and I think there is a genuine
need for it.  Beryl has added an ipcs system which
I think handles this sort of thing for the plugins.
These hints should be available to all plugins,
window privates are only available to the individual
plugin.

2. Individual window settings.  A lot of the plugins
are starting to have window specific settings, these
are normally set based on the class, title etc.
So far they have been using a string like this to
configure an individual window class.

Maybe something could be standardized in the
core to accommodate these requirements?
