/**
 * This <code>Paint</code> interface defines how color patterns
 * can be generated for {@link Graphics2D} operations.  A class
 * implementing the <code>Paint</code> interface is added to the
 * <code>Graphics2D</code> context in order to define the color
 * pattern used by the <code>draw</code> and <code>fill</code> methods.
 * <p>
 * Instances of classes implementing <code>Paint</code> must be
 * read-only because the <code>Graphics2D</code> does not clone
 * these objects when they are set as an attribute with the
 * <code>setPaint</code> method or when the <code>Graphics2D</code>
 * object is itself cloned.

     * Creates and returns a {@link PaintContext} used to
     * generate the color pattern.
     * The arguments to this method convey additional information
     * about the rendering operation that may be
     * used or ignored on various implementations of the {@code Paint} interface.
     * A caller must pass non-{@code null} values for all of the arguments
     * except for the {@code ColorModel} argument which may be {@code null} to
     * indicate that no specific {@code ColorModel} type is preferred.
     * Implementations of the {@code Paint} interface are allowed to use or ignore
     * any of the arguments as makes sense for their function, and are
     * not constrained to use the specified {@code ColorModel} for the returned
     * {@code PaintContext}, even if it is not {@code null}.
     * Implementations are allowed to throw {@code NullPointerException} for
     * any {@code null} argument other than the {@code ColorModel} argument,
     * but are not required to do so.
     *
     * @param cm the preferred {@link ColorModel} which represents the most convenient
     *           format for the caller to receive the pixel data, or {@code null}
     *           if there is no preference.
     * @param deviceBounds the device space bounding box
     *                     of the graphics primitive being rendered.
     *                     Implementations of the {@code Paint} interface
     *                     are allowed to throw {@code NullPointerException}
     *                     for a {@code null} {@code deviceBounds}.

     *                     Implementations of the {@code Paint} interface
     *                     are allowed to throw {@code NullPointerException}
     *                     for a {@code null} {@code userBounds}.
     * @param xform the {@link AffineTransform} from user
     *              space into device space.
     *                     Implementations of the {@code Paint} interface
     *                     are allowed to throw {@code NullPointerException}
     *                     for a {@code null} {@code xform}.
