within OnDraw, to set the device origin for the device context according to the current
scroll position.
+A wxScrolledWindow will normally scroll itself and therefore its child windows as well. It
+might however be desired to scroll a different window than itself: e.g. when designing a
+spreadsheet, you will normally only have to scroll the (usually white) cell area, whereas the
+(usually grey) label area will scroll very differently. For this special purpose, you can
+call \helpref{SetTargetWindow}{wxscrolledwindowsettargetwindow} which means that pressing
+the scrollbars will scroll a different window.
+
+Note that the underlying system knows nothing about scrolling coordinates, so that all system
+functions (mouse events, expose events, refresh calls etc) as well as the position of subwindows
+are relative to the "physical" origin of the scrolled window. If the user insert a child window at
+position (10,10) and scrolls the window down 100 pixels (moving the child window out of the visible
+area), the child window will report a position of (10,-90).

scrolling is the physical transfer of bits up or down the
screen when a scroll event occurs. If the application scrolls by a
variable amount (e.g. if there are different font sizes) then physical
-scrolling will not work, and you should switch it off.

\wxheading{Remarks}
The first pair of parameters give the number of pixels per `scroll step', i.e. amount
necessary to derive a new class from wxWindow, overriding {\bf OnSize} and
adjusting the scrollbars appropriately.
