From e5555d7a749c90288463ed1c294f58963c607e52 Mon Sep 17 00:00:00 2001

Subject: Revert "Reject trapezoids where top (botttom) is above (below) the edges"
Cairo 1.10 will sometimes generate trapezoids like this, so we can't
consider them invalid. Fixes bug 45009, reported by Michael Biebl.
This reverts commit 2437ae80e5066dec9fe52f56b016bf136d7cea06.
