ArcDistortBrush(id, angle1[, angle2, rtop, rbottom, smooth])
id. The angle1 argument specifies the angle over which the brush
should be arc'ed. The optional arguments can be used to control further
parameters for the arc distortion. angle2 can be used to rotate the
brush around the circle, and the rtop and rbottom values can be used
to adjust the top and bottom radii settings. Finally, the optional
argument smooth can be used to enable antialiased pixel interpolation
which leads to a smoother appearance but takes longer to calculate.
