<!--
This test consists of a pair of sub-tests which complements each other.
Logically, the test should verify 1.block flow direction, 2.inline direction
and 3.glyph orientation. The "Ahem" sub-test comes first and checks 1. and 2. ,
whereas "glyph" sub-test comes later and also checks 3.
-->
<p>Test passes if a pair of rectangles is <strong>identical</strong> including <strong>layout</strong> and <strong>orientation</strong>.</p>
