@class wxVarScrollHelperBase
This class provides all common base functionality for scroll calculations
shared among all variable scrolled window implementations as well as
automatic scrollbar functionality, saved scroll positions, controlling
target windows to be scrolled, as well as defining all required virtual
functions that need to be implemented for any orientation specific work.
Documentation of this class is provided specifically for referencing use
of the functions provided by this class for use with the variable scrolled
windows that derive from here. You will likely want to derive your window
from one of the already implemented variable scrolled windows rather than
from wxVarScrollHelperBase directly.

@class wxVScrolledWindow
In the name of this class, "V" may stand for "variable" because it can be
used for scrolling rows of variable heights; "virtual", because it is not
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.
In any case, this is a generalization of wxScrolled which can be only used
when all rows have the same heights. It lacks some other wxScrolled
features however, notably it can't scroll specific pixel sizes of the
window or its exact client area size.
To use this class, you need to derive from it and implement the
OnGetRowHeight() pure virtual method. You also must call SetRowCount() to
let the base class know how many rows it should display, but from that
moment on the scrolling is handled entirely by wxVScrolledWindow. You only
need to draw the visible part of contents in your @c OnPaint() method as
usual. You should use GetVisibleRowsBegin() and GetVisibleRowsEnd() to
select the lines to display. Note that the device context origin is not
shifted so the first visible row always appears at the point (0, 0) in
physical as well as logical coordinates.
@section vscrolledwindow_compat wxWidgets 2.8 Compatibility Functions
The following functions provide backwards compatibility for applications
originally built using wxVScrolledWindow in 2.6 or 2.8. Originally,
wxVScrolledWindow referred to scrolling "lines". We now use "units" in
wxVarScrollHelperBase to avoid implying any orientation (since the
functions are used for both horizontal and vertical scrolling in derived
classes). And in the new wxVScrolledWindow and wxHScrolledWindow classes,
we refer to them as "rows" and "columns", respectively. This is to help
clear some confusion in not only those classes, but also in
wxHVScrolledWindow where functions are inherited from both.
You are encouraged to update any existing code using these function to use
the new replacements mentioned below, and avoid using these functions for
any new code as they are deprecated.
@beginTable
@row2col{ <tt>size_t %GetFirstVisibleLine() const</tt>,
Deprecated for GetVisibleRowsBegin(). }
@row2col{ <tt>size_t %GetLastVisibleLine() const</tt>,

slight design flaw in that it was possible to return
<tt>(size_t)-1</tt> (ie: a large positive number) if the scroll
position was 0 and the first line wasn't completely visible. }
