GameZero opens a window four times bigger than defined

[rmsrosa]

Hi, following up the discussion on JuliaCon discord, here is the report of the bug I found on my system. The game only uses a quarter of the window. I think it actually displays a window which is twice wide and twice taller than defined.

I attach screenshots of two of the games form SquidSinker/GZExamples. They define HEIGHT = 600 and WIDTH = 600, but the windows have twice the height and twice the width, as seen from the pixel count on the screenshots.

Here is the info of my set up:

P.S.: The sound issue that I also mentioned didn't happen again. Sound is coming out fine. I might have done something wrong. Great, one less problem!
