void CAIRO_GAL_BASE::DrawArcSegment ( const VECTOR2D aCenterPoint,
double  aRadius,

Draw an arc segment.

This method differs from DrawArc() in what happens when fill/stroke are on or off. DrawArc() draws a "pie piece" when fill is turned on, and a thick stroke when fill is off. DrawArcSegment() with fill on behaves like DrawArc() with fill off. DrawArcSegment() with fill off draws the outline of what it would have drawn with fill on.

TODO: Unify Arc routines

Parameters
aCenterPointis the center point of the arc.
aRadiusis the arc radius.
aStartAngleis the start angle of the arc.
aEndAngleis the end angle of the arc.
aWidthis the thickness of the arc (pen size).
