/* This testcase verifies that animated values of "wider" and "narrower" for
"font-stretch" have the expected effect, across all possible inherited
values of the property.
XXXdholbert Currently, we don't support animating relative values of
font-stretch, so most of the tests here use todo_is() rather than is().
