+Subject: [PATCH] mi: Partial pie-slice filled arcs may need more space for
+ spans
+
+The mi filled arc code estimates that a filled arc will produce no
+more spans than the arc is tall. This is true for most arcs except
+for pie-slice arcs strictly between 180 and 360 degrees where the missing
+portion of the arc faces up or down such that we get two spans on some
+scanlines.
+
+For those, we need to reserve room for another height/2 spans. This
+patch just does it for all partial pie-sliced arcs to make the test
+easier to understand; it's just over-allocating a bit of memory, so
+that's safe.
