/*
    Python3 definition file to consistently map the code to Python 2 or
    Python 3.

    PyInt and PyLong were merged into PyLong in Python 3, so all PyInt functions
    are mapped to PyLong.

    PyString, on the other hand, was split into PyBytes and PyUnicode. We map
    both back onto PyString, so use PyBytes or PyUnicode where appropriate. The
    only exception to this is _imagingft.c, where PyUnicode is left alone.
