        Draws a collection of paths selecting drawing properties from
        the lists *facecolors*, *edgecolors*, *linewidths*,
        *linestyles* and *antialiaseds*. *offsets* is a list of
        offsets to apply to each of the paths.  The offsets in
        *offsets* are first transformed by *offsetTrans* before being
        applied.  *offset_position* may be either "screen" or "data"
        depending on the space that the offsets are in.

        This provides a fallback implementation of
        :meth:`draw_path_collection` that makes multiple calls to
        :meth:`draw_path`.  Some backends may want to override this in
        order to render each set of path data only once, and then
        reference that path multiple times with the different offsets,
        colors, styles etc.  The generator methods
        :meth:`_iter_collection_raw_paths` and
        :meth:`_iter_collection` are provided to help with (and
        standardize) the implementation across backends.  It is highly
        recommended to use those generators, so that changes to the
        behavior of :meth:`draw_path_collection` can be made globally.
