static booleandrawGradient(java.awt.Component c, java.awt.Graphics g, java.lang.String key, int x, int y, int w, int h, boolean vertical)
Draws a radial type gradient. The gradient will be drawn vertically if vertical is true, otherwise horizontally. The UIManager key consists of five values: r1 r2 c1 c2 c3. The gradient is broken down into four chunks drawn in order from the origin.
  1. Gradient r1 % of the size from c1 to c2
  2. Rectangle r2 % of the size in c2.
  3. Gradient r1 % of the size from c2 to c1
  4. The remaining size will be filled with a gradient from c1 to c3.
