Creates a new radial gradient cairo_pattern_t between the two circles defined by (cx0, cy0, radius0) and (cx1, cy1, radius1).
Before using the gradient pattern, a number of color stops should be defined using Cairo::Gradient::add_color_stop_rgb() or Cairo::Gradient::add_color_stop_rgba().

| cy0 | y coordinate for the center of the start circle | 
| radius0 | radius of the start circle | 
| cx1 | x coordinate for the center of the end circle | 
| cy1 | y coordinate for the center of the end circle | 
| radius1 | radius of the end circle |
