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 |
