    Returns WKT text of the geometry according to the given precision (an
    integer or a string).  If the precision is an integer, then the decimal
    places of coordinates WKT will be truncated to that number:

     >>> from django.contrib.gis.geos import Point
     >>> pnt = Point(5, 23)
     >>> pnt.wkt
     'POINT (5.0000000000000000 23.0000000000000000)'
     >>> precision_wkt(pnt, 1)
     'POINT (5.0 23.0)'

    If the precision is a string, it must be valid Python format string
    (e.g., '%20.7f') -- thus, you should know what you're doing.
    s>   precision_wkt() is deprecated in favor of the WKTWriter class.t
