+/*!
+ Moves the contents (all existing drawing as well as all all child wxWindow) by the specified
+ amount expressed in the wxWindow's own coordinate system. This is used to implement scrolling
+ but the usage is rather interesting. When scrolling right (e.g. increasing the value of
+ the scroller) you must give a negative delta x (e.g. moving the contents LEFT). Likewise,
+ when scrolling the window down, increasing the value of the scroller, you give a negative
+ delta y which moves the contents up.
+
+ wxCocoa notes: To accomplish this trick in Cocoa we basically do what NSScrollView would
+ have done and that is adjust the content view's bounds origin. The content view is somewhat
+ confusingly the NSClipView which is more or less sort of the pImpl for NSScrollView
+ The real NSView with the user's content (e.g. the "virtual area" in wxWidgets parlance)
+ is called the document view in NSScrollView parlance.
+
+ The bounds origin is basically the exact opposite concept. Whereas in Windows the client
+ coordinate system remains constant and the content must shift left/up for increases
+ of scrolling, in Cocoa the coordinate system is actually the virtual one. So we must
+ instead shift the bounds rectangle right/down to get the effect of the content moving
+ left/up. Basically, it's a higher level interface than that provided by wxWidgets
+ so essentially we're implementing the low-level move content interface in terms of
+ the high-level move the viewport (the bounds) over top that content (the document
+ view which is the virtual area to wx).
+
+ For all intents and purposes that basically just means that we subtract the deltas
+ from the bounds origin and thus a negative delta actually increases the bounds origin
+ and a positive delta actually decreases it. This is absolutely true for the horizontal
+ axis but there's a catch in the vertical axis. If the content view (the clip view) is
+ flipped (and we do this by default) then it works exactly like the horizontal axis.
+ If it is not flipped (i.e. it is in postscript coordinates which are opposite to
+ wxWidgets) then the sense needs to be reversed.
+
+ However, this plays hell with window positions. The frame rects of any child views
+ do not change origin and this is actually important because if they did, the views
+ would send frame changed notifications, not to mention that Cocoa just doesn't really
+ do scrolling that way, it does it the way we do it here.
+
+ To fix this we implement GetPosition for child windows to not merely consult its
+ superview at the Cocoa level in order to do proper Cocoa->wx coordinate transform
+ but to actually consult is parent wxWindow because it makes a big difference if
+ the parent is scrolled. Argh. (FIXME: This isn't actually implemented yet)
