 The {{{Region()}}} objects are missing a method for saving the Region
 settings to a Region file.
 As a result, it is not really possible to use {{{WIND_OVERRIDE}}} with
 {{{Region}}} objects without resorting to use `g.region`. The following
 snippet is a possible implementation of a {{{save()}}} method:

 {{{
     def save(self, filename):
         """
         Save the Region settings to the specified Region file.

         This is the equivalent of `g.region save=filename --overwrite`

         The region file will be created inside the `$MAPSET/windows`
 directory.
         """
         if not grass.legal_name(filename):
             raise ValueError("Illegal filename: %s", filename)
         self.adjust()
         ret = libgis.G_put_element_window(self.byref(), "windows",
 filename)
         if ret < 0:
             raise ValueError("Couldn't save the region settings at: %s",
 filename)
 }}}
