painting-order-underline-001 = Ahem 'underline' decoration painting order and descender
  • This test checks that underlining painting is done before glyphs are painted; therefore, if the underlining crosses the descenders (glyphs like 'g', 'j', 'p', 'q', 'y' have a descender), then the descender part must overlap the underline.
