Switching themes when running Metacity window manager doesn't work

[Martin Wimpress ]

When running the Metacity window manager (a supported option in MATE Tweak), switch theme in MATE Appearance Preferences doesn't apply the theme changes to the window decorations.

I'm accepting this because it's no worse than what is there currently, but spawning the gsettings binary instead of using the API we have in GLib is really nasty. There are a some ways I can think of to deal with this:

  - Use the g_settings_schema_source_get_default() and look at the returned GSettingsSchemaSource (g_settings_schema_source_lookup(), g_settings_schema_has_key()) to see if it has the properties you want.
  - Look at `metacity --version' to decide what to try to do.
  - Require a particular metacity version as a lower bound and don't have cases for older ones.

Thanks for the feedback.

The improvements you've identified are on the roadmap for MATE next, in fact adopting Metacity as a first class component is also up for discussion.
