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.

X Server
The X server accepts requests from client applications to create windows,
which are (normally rectangular) "virtual screens" that the client program
can draw into.
Windows are then composed on the actual screen by the X server
(or by a separate composite manager) as directed by the window manager,
which usually communicates with the user via graphical controls such as buttons
and draggable titlebars and borders.
