Executing external programs (e.g. using g.list to generate a list of
maps) doesn't work. The actual OpenGL rendering works fine.

The main issue here is that gis.m would need to use the immediate
rendering provided by the new version of libraster. The MSVC runtime
doesn't include socket functions (and Windows itself doesn't support
Unix-domain sockets), so using a separate PNG driver won't work.
