Improper canvas size when using scaled resolutions on macOS about canvas HOT 1 OPEN

Hi,

sorry for the really late response. I couldn't test it right away, and then lost track of it...

Anyway, in case it is still relevant, yes it is due to the display scaling. When you create a window with some size, macOS just automatically scales it up if you have set the display to scale. Since that means you have a higher physical resolution in the window, you need to then query the actual size by using the cv.Width() and cv.Height() functions.

If you want to create a window with a certain physical resolution, regardless of the scale factor, then you will have to find out the scale factor somehow. I know on iOS you can query it (on UIScreen there is a scale property), but I don't know if there is an equivalent for macOS.
