Resize grips in Metacity on Precise are 1px

Upstream appears not to care. We should just divert the Ambiance theme's XML and change them to 3px, which greatly improves this (see the first comment in the upstream bug).

#354 notwithstanding.

I'd like to use this as a test package for either the hackathon or Debathena training, so now would be a good time to bikeshed about whether to change the borders to 2px or 3px. I chose 3. Relevant changes that need to be made:
