Helper class to ensure that the Mac style in Widgets and Quick
draw their NSViews and NSCells with the correct appearance,
as the native controls use NSAppearance.currentDrawingAppearance
instead of NSApp.effectiveAppearance when drawing.
Due to the duplicated class hierarchies between Widgets and Quick
for the styles, with the Quick styles missing the QWidget pointer
in the function parameters, we have to opt for an awkward macro
to solve this.
