MacOS: fix necessary for 10.14.2 public beta 3

Browse Source 
Apple keeps changing how windows are drawn under 10.14 Mojave, even between minor 
releases! 
This change is required to correctly update a GL window moved from a non-retina to
a retina display under 10.14.2 public beta 3 (glpuzzle shows the problem).
It's unsure if it will still be necessary with 10.14.2, or later versions, but the change
does no harm if it's not necessary.
