<para>
Creates a new radial gradient <type>CairoPattern</type> between the two circles defined by (x0, y0, r0)
and (x1, y1, r1). Before using the gradient pattern, a number of color stops should be defined
using <methodname>CairoRadialGradient::addColorStopRgb</methodname>
or <methodname>CairoRadialGradient::addColorStopRgba</methodname>.
</para>
<para>
Note: The coordinates here are in pattern space. For a new pattern, pattern space is identical to user
space, but the relationship between the spaces can be changed with <methodname>CairoRadialGradient::setMatrix</methodname>.
