[ubuntu-art] Submission Tweaks

[John Baer]

Metacity

I made a minor tweak to the Impression Metacity theme. The close
prelight presentation was very bold so I backed it off by reducing the
size of the band.

The prelight band widths are now:

Close: 7px
Max: 3px
Min: 5px

By default the Widgets are 11px. In prelight they grow to 14px. When
clicked they fade to 11.7px although visually they appear smaller.

Backgrounds

I also added a sunrise/sunset tint to the Jaunty Highway background.

I'm not satisfied with the Jaunty Message background submission and want
to do something better. I hope to have it posted by 4/12.
