summary of changes to this test (since it's hard to tell with all the
reformatting):

1. this size is larger (so we don't run into minimum size issues for big
shadows)

2. there's a loop that iterates over all shadow types

3. stroke is only used for asset-based shadows

4. kHeightDifference check updated to work for big shadow
