+/*
+ This class is strongly influenced by wxVScrolledWindow. In fact, much of
+ code is line for line the same except it EXPLICITLY states which axis is
+ being worked on. Like wxVScrolledWindow, this class is here to provide
+ an easy way to implement variable line sizes. The difference is that
+ wxVScrolledWindow only works with vertical scrolling. This class extends
+ the behavior of wxVScrolledWindow to the horizontal axis in addition to the
+ vertical axis.
+
+ The scrolling is also "virtual" in the sense that line widths and heights
+ only need to be known for lines that are currently visible.
+
+ Like wxVScrolledWindow, this is a generalization of the wxScrolledWindow
+ class which can be only used when all horizontal lines have the same width
+ and all of the vertical lines have the same height. Like wxVScrolledWinow
+ it lacks some of wxScrolledWindow features such as scrolling another window
+ or only scrolling a rectangle of the window and not its entire client area.
+
+ If only vertical scrolling is needed, wxVScrolledWindow is recommended
+ because it is simpler to use (and you get to type less).
+
+ There is no wxHScrolledWindow but horizontal only scrolling is implemented
+ easily enough with this class. If someone feels the need for such a class,
+ implementing it is trivial.
