window: Parse _GTK_THEME_VARIANT property
Since version 3.0, GTK+ has support for style variants. At the moment, themes may provide a dark variant, which can be requested by applications via GtkSettings. The requested variant is exported to X11 via the _GTK_THEME_VARIANT property - support this property, in order to pick up the correct style variant in the future. https://bugzilla.gnome.org/show_bug.cgi?id=645355 NOTE: Patch is adapted for marco. upstream commit: https://gitlab.gnome.org/GNOME/metacity/commit/341d0945
