produce ugly spikes in the contours.  The problem was that screen
coordinates were being passed as data coordinates when the contour was
split to add room for the label.

Fix for bug #3029.

The FreeType class does not override the ``get_extension`` method, by default this method will return None.

When calling the ``_check_for_pkg_config`` method a new extension will be created that what won't contain the original flags added by the ``add_flags`` method.
