   In the name of this class, "V" may stand for "variable" because it can be
   used for scrolling lines of variable heights; "virtual" because it is not
   necessary to know the heights of all lines in advance -- only those which
   are shown on the screen need to be measured; or, even, "vertical" because
   this class only supports scrolling in one direction currently (this could
   and probably will change in the future however).

   In any case, this is a generalization of the wxScrolledWindow class which
   can be only used when all lines have the same height. It lacks some other
   wxScrolledWindow features however, notably it currently lacks support for
   horizontal scrolling; it can't scroll another window nor only a rectangle
   of the window and not its entire client area.

    This class has two main differences from a regular listbox: it can have an
    arbitrarily huge number of items because it doesn't store them itself but
    uses OnDrawItem() callback to draw them and its items can have variable
    height as determined by OnMeasureItem().

    It emits the same events as wxListBox and the same event macros may be used
