Is this to test the positioning of overflow scroll controls? Or, just general repainting behavior?

I would like to verify this, yes, but mainly I want to ensure that when we start automatically opting into composited scrolling, that we don't introduce any unexpected regressions in these tests.

Updated test expectations.

What are the failures here caused by? I thought this flag didn't do anything yet.

The failures are due to missing test expectations. The failing tests also fail for chromium in general. I've updated the expectations file with this latest patch.

Updated test expectations.

Oh, right! I keep forgetting that expectations don't get inherited for virtual test suites.  R=me.

It's probably well past time I fixed that.

Reverted r137645 for reason:

Breaks some overflow layout tests

This should be --enable-accelerated-overflow-scroll to match Chromium.  I also think you need to add this option to DRT parsing in Tools/DumpRenderTree/chromium/DumpRenderTree.cpp.

Gah, of course! This latest patch has the correct flag, and I've confirmed that my plumbing does indeed make it in.
