/** Resizes a gradient to fill the width and height available. If the
 * gradient is left to right it will be resized to fill the entire width.
 * If the gradient is top to bottom it will be resized to fill the entire
 * height. If the gradient is on an angle it will be resized to go from
 * one corner to the other of the rectangle formed by (0,0 -> width,height).
 *
 * This method can resize java.awt.GradientPaint, java.awt.LinearGradientPaint,
 * and the LinearGradientPaint implementation from Apache's Batik project. Note,
 * this method does not require the MultipleGradientPaint.jar from Apache to
 * compile or to run. MultipleGradientPaint.jar *is* required if you want
 * to resize the LinearGradientPaint from that jar.
 *
 * Any paint passed into this method which is not a kind of gradient paint (like
 * a Color or TexturePaint) will be returned unmodified. It will not throw
 * an exception. If the gradient cannot be resized due to other errors the
 * original paint will be returned unmodified. It will not throw an
 * exception./*from w  w w.j  a  v a  2s .  com*/
