+   This testcase checks that we don't clamp negative opacity values to their
+   valid range [0,1] until *after* we've done animation & interpolation.
+   If we clamped intermediate results too early (e.g. after parsing, during
+   interpolation, or right after we add the first animation's interpolated
+   value), we'd end up with the wrong intermediate opacity values here.
