In my quest to understand how a class from wxWidgets is wrapped I took at
look at wxSlider as it shares the same class hierarchy as wxPropertyGrid and
'slider' is a fairly distinct term.

Searching for 'slider' in the wxHaskell code I extracted the following
references to it.
Does this look complete? If anyone could comment further on what function
each part provides I'd be very grateful.
