Disable closed contour check in the test harness.

The check was actually half-broken from the beginning and
until df83ee4; the thick red line was rendered properly but
the error text was rendered with width 0, which by chance worked
on some GL implementations. That commit has fixed the underlying
bug but left the text line width at 0 to avoid test breakage.

This commit fixes the bug, turns off the check completely, and
updates the tests to account for breakage.
