public abstract Type get_type_from_name (Builder builder, string type_name)
Try to lookup a `GType` via the its name.
See get_type_from_name for more details. The C implementation will
use from_name and if that fails try to guess the correct function name for registering the type and
then use dlsym
to load it. The default implementation just tries from_name and otherwise
fails.
