gtk2/gdk/quartz/gdkevents-quartz.c
John Ralls aeec73f53f Refine GdkQuartzNSWindow convertPointToScreen: 
and convertPointFromScreen:, making them handle all MacOS versions
so that all of the if-deffing happens in the function definitions.
This happens to fix issue 1518 because it turns out that contrary
to the annotation in the 10.14 nNSWindow.h, convertPointToScreen and
convertPointFromScreen originate in 10.14, not 10.12.

Closes: https://gitlab.gnome.org/GNOME/gtk/issues/1518

NSEventTypeMagnfiy and NSEventTypeRotate to the GDK_TOUCHPAD_PINCH event.
The normal behavior of the OSX events is that they produce as sequence of
1 x NSEventPhaseBegan,
n x NSEventPhaseChanged,
1 x NSEventPhaseEnded
This can happen for both the Magnify and the Rotate events independently.
As both events are summarized in one GDK_TOUCHPAD_PINCH event sequence, a
little state machine handles the case of two NSEventPhaseBegan events in
a sequence, e.g. Magnify(Began), Magnify(Changed)..., Rotate(Began)...
such that PINCH(STARTED), PINCH(UPDATE).... will not show a second
PINCH(STARTED) event.
