IIRC it was because it duplicated most of the code from 
wxVScrolledWindow instead of refactoring and sharing as much as possible 
between the two classes.  The original author was going to come back 
with a new patch but never did.  IMO it would also make sense to just 
add variable sized horizontal scrolling to wxVScrolledWindow and make 
the V stand for Variable instead of Vertical.

Have you given any thought to implementing a Python version of 
wxVScrolledWindow + horizontal scrolling?
