+/*
+General observation about Cocoa screen coordinates:
+It is documented that the first object of the [NSScreen screens] array is the screen with the menubar.
+
+It is not documented (but true as far as I can tell) that (0,0) in Cocoa screen coordinates is always
+the BOTTOM-right corner of this screen. Recall that Cocoa uses cartesian coordinates so y-increase is up.
+
+It isn't clearly documented but visibleFrame returns a rectangle in screen coordinates, not a rectangle
+relative to that screen's frame. The only real way to test this is to configure two screens one atop
+the other such that the menubar screen is on top. The Dock at the bottom of the screen will then
+eat into the visibleFrame of screen 1 by incrementing it's y-origin. Thus if you arrange two
+1920x1200 screens top/bottom then screen 1 (the bottom screen) will have frame origin (0,-1200) and
+visibleFrame origin (0,-1149) which is exactly 51 pixels higher than the full frame origin.
+
+In wxCocoa, we somewhat arbitrarily declare that wx (0,0) is the TOP-left of screen 0's frame (the entire screen).
+However, this isn't entirely arbitrary because the Quartz Display Services (CGDisplay) uses this same scheme.
+This works out nicely because wxCocoa's wxDisplay is implemented using Quartz Display Services instead of NSScreen.
