draw-ellipse in dc<%>

Draws an ellipse contained in a rectangle. The current pen is used for the outline, and the current brush is used for filling the shape.

If both the pen and brush are non-transparent, the ellipse is filled with the brush before the outline is drawn with the pen. The filling and outline meet so that no space is left between them, but the precise overlap between the filling and outline is platform- and size-specific. Typically, the regions drawn by the brush and pen overlap. More generally, the pen is centered over the outline of the ellipse, rounding toward the center in unsmoothed mode.
