+// necessary to know the heights of all rows in advance -- only those which
+// are shown on the screen need to be measured; or even "vertical", because
+// this class only supports scrolling vertically.

+// wxScrolledWindow features however, notably it can't scroll only a rectangle
+// of the window and not its entire client area.
