Ran into a bug from my old gradient stuff. Basically when determining whether or
not we are in the Edge case we are in a world that is scaled be the radius of
the first circle. When checking this in the ASSERT we were not doing it in the
scaled world.

A revert of this CL has been created in
https://codereview.chromium.org/320573002/ by egdaniel@google.com.

The reason for reverting is: changed assert is failing.

Fix to my fix of the assert. Now passing a subset of the bots that failed on the
original commit
