#25 PyOpenGL_accelerate fails to compile with Python 3.7+

[Tomi Maila]

The installation of PyOpenGL_accelerate fails to install on Python 3.7 on Windows 10 and later becasue the _ts struct in Python 3.7 was modified and no longer has the same members.

> pip3 --no-cache-dir install PyOpenGL_accelerate
