We have a relatively simple test case for the gradients with CSS
animation, but we've been asked to keep distribution of it low for the
time being, as it's a prototype for an upcoming site design.  I can send
it to individual people for serious testing.

We also have a (very) simplified version of the AOL UK website which
triggers the atlas-maps problem.  I've attached that one.
