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.
