24/**
25 * This class is used to control the shape and color of the drawing operations
26 * performed by a PNMPainter object.
27 *
28 * Normally, you don't create a PNMBrush directly; instead, use one of the
29 * static PNMBrush::make_*() methods provided here.
30 *
31 * A PNMBrush is used to draw the border of a polygon or rectangle, as well as
32 * for filling its interior. When it is used to draw a border, the brush is
33 * "smeared" over the border; when it is used to fill the interior, it is
34 * tiled through the interior.
