If we are on a HiDPI display, we adjust the viewport size.

This seems only relevant on macOS but a test for get_viewport_size() is added to try and make sure it doesn’t affect other archs too. This addresses #303 on macOS.

@DidierMalenfant thanks for taking the time for this PR

Probably you have done it, but, can you confirn that the following interactive tests work as expected?

• test/test_aspect_4_3_to_fullscreen.py
• test/test_aspect_16_9_to_fullscreen.py
• test/test_aspect_ratio_on_resize.py
• test/test_coords.py
• test/test_unscaled_win_resize.py

(I dont have access to a retina display)

Thanks @ccanepa I had checked the unit tests but not the interactive ones. Off to do that now and make sure everything is good on that end too.

I think your solution is a wrong solution. It didnot solve the problem.

I checked the documentation, but I couldn't find an API for how to adjust the size of the scene

Thanks
Just add this patch，it get ok
