    mi: Partial pie-slice filled arcs may need more space for spans · 41932dfb
    Keith Packard authored
    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
    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.
