[ubuntu-art] [Breathe] Consistent shadowing.

[Cory K.]

This is becoming an increasing issue. You can look on the submission
page alone and see that between our 3 current artists shadows are different.

We *have* to keep them in-line with what Sebastien does. Oliver and
Daniel please look over Sebastien's icons and base off of them.

I really don't want to have to go back and inspect these all myself. We
need to do it correctly from the start.
