Speed up gnome/metacity by turning on wireframe mode

[Chu Tan <chujtan gmail com>]

I started out just wanting to turn on wireframe mode, because I can't
stand firefox making the windows not responsive whenever resizing.

Run gconf-editor  (if not available, yum install gconf-editor)

Browse to 
/apps/metacity/general/

and create a new boolean type key "reduced_resources", set to true.

Here's the comments that comes with the schema:

If true, metacity will give the user less feedback by using wireframes,
avoiding animations, or other means. This is a significant reduction in
usability for many users, but may allow legacy applications to continue
working, and may also be a useful tradeoff for terminal servers.
However, the wireframe feature is disabled when accessibility is on.

As far as I know, it is not possible to just turn on wireframe mode
alone, and retain things like animation.
