[PATCH] ui/cocoa: Fixed modeswitching glitch in zoomed fullscreen mode

[Imran Yusuff]

This applies only on macOS using cocoa UI library.

In zoom-to-fit fullscreen mode, upon graphics mode switch,
the viewport size is wrong, and the usual consequence
is only a part of the screen is visible. One have to exit
and reenter fullscreen mode to fix this.

This is reproducible by setting up a Windows 3.11 system,
booting into DOS, enable zoom-to-fit, enter fullscreen mode and
start Windows by 'win'. Then you can see only part of the screen.

This commit fixes this problem, by including one line of code
which is from the fullscreen mode initialization.
