A symbolizer with a {{{render_on_context(cairo_context, feature, view_transform, proj_transform)}}} virtual method which could be overriden in Python would be very useful for custom symbolizers and prototyping of new functionality before implementing it in C++.

This really needs a WKB writer so geometries can be read inside the python method.
