+		<p><b>Bugfix: Triangles render incorrectly in the presence of focal blur.</b></p>
+		<p>
+		Triangular grids are just square grids with a diagonal cut line.  They have
+		special-case code to make sure that only samples on one side of the cut line
+		actually hit the surface.  The circle of confusion offset needs to be taken
+		into account when performing the cut line test, otherwise some samples
+		incorrectly miss and others incorrectly hit the surface.
+		</p>
+		<p>
+		The test case contains two triangles which fit together to make a
+		white square; the centre is in focus.  With the bug in evidence, there
+		will be an obvious blurry black diagonal across the square from top to
+		bottom.  The top-right side was also sharp rather than blurred.
