Stabilize empty rect handling in EnclosingRect.
We want empty Rects to have empty enclosing rects, per
https://chromiumcodereview.appspot.com/15233003, but we would
prefer this to not bounce around based on floating point calculations
accumulating some epsilon sized errors.
roundOut in SKIA does not have either the former or the new behavior,
so we are drifting apart from an underlying expectation, and should be
careful this doesn't cause future inconsistencies between paths,
like mainthread/ impl thread.
