Create a C++ wrapper for the C instance. This C++ instance should then be given to a RefPtr.

Adds an opaque color stop to a gradient pattern. The offset specifies the location along the gradient's control vector. For example, a linear gradient's control vector is from (x0,y0) to (x1,y1) while a radial gradient's control vector is from any point on the start circle to the corresponding point on the end circle. The color is specified in the same way as in Context::set_source_rgb().
