Enable compositing when a CSS filter is animating

Now that we have hardware accelerated filters, and support for animation (at least on OS X), we should turn on compositing for animated filters.

This patch seems too easy (but it works as verified by CA_PRINT_TREE). Simon, have I missed something?

Patch Don't you need to test the layer output (layerTreeAsText())?. You'll also have to be careful that the first animating thing doesn't throw the rest into layers for the test.

Added a new test for that, but I've run into a problem.

I've added a couple of non-filtered elements. The problem is that the fix doesn't work in WebKit2. It works fine in WK1, but with WK2 the layer updates don't get painted. I do see the object jump into compositing mode, but only repaint if I do something tricky in the inspector (like highlight the object, then it paints that frame once). I've attached a simple example that exercises the feature. Hover over the first blue rectangle and it should animate. Doesn't work in WK2.

Style checker failure is because I have the semicolon for the return statement on a blank line, due to the #if. I think that's ok.

Patch Patch no worky in the case where an element is already composited. Also, layer tree output is platform-specific (as shown in failing test for chromium)

The platform that will produce interesting results for the layout tests is mac-future, but those results are not included here.

I'm not sure why the chromium tests are failing. Since the results are platform specific anyway, I'll put them in the platform dir.
