AttributeError: 'Window' object has no attribute 'get_viewport_size' on Ubuntu 18.04 LTS (64-Bit) with system-provided pyglet package about minecraft

I created a pull request that fixes this problem: #109
It is not a perfect solution, because it uses window size, not viewport size, but it works for me.

I'll look into this later today. Your commit unfortunately reverts the commit I made 8 months ago to fix an issue that using window size causes on Mac. It shouldn't be to much trouble to implement a check and apply different solutions so that one package can work for both Mac and Linux.

I think you can check if method get_viewport_size exists and depending on the result of the check use this method or window size.
