Use Custom Theme in GNOME Shell 3.6 (Ubuntu 12.10)

Here's a simple solution for you who use GNOME Shell desktop environment (GNOME 3.6) to make custom themes (especially metacity/window decoration themes) work on GNOME Shell 3.6 desktop in latest Ubuntu 12.10 (Quantal Quetzal).

Some people prefer GNOME Shell desktop environment over the default Unity desktop in latest Ubuntu 12.10. The DE comes with the default Adwaita theme from GNOME Team, which is clean and beautiful theme, but still, people want the ability to use custom themes to personalize for their own desktop.

In previous version of GNOME Shell, people can choose different themes by putting their cutom themes in user folder (~/.themes) and then easily activate them via a theme changer utility app like GNOME Tweak Tool (Advanced Settings). Unfortunately, in the latest stable realease (GNOME 3.6), this ability to use custom theme is not that easy anymore, which is I think a regression. Below is a screenshot:

Like you can see on the screenshot above, I activated custom themes (zonColor) for window border/titlebar theme, GTK theme, and GNOME Shell theme. The GTK theme and GNOME Shell theme work, but not the window (metacity/mutter) theme; it still show the default theme, despite what I choose via GNOME Tweak Tool app window.

So, how to make custom themes (especially metacity) work on latest GNOME Shell 3.6?
