"""
This module implements various forms of generic buttons, meaning that
-they are not built on native controls but are self-drawn.
-
-The GenButton is the base. It acts like a normal button but you
-are able to better control how it looks, bevel width, colours, etc.
-
-GenBitmapButton is a button with one or more bitmaps that show
-the various states the button can be in.
-
-GenToggleButton stays depressed when clicked, until clicked again.
-
-GenBitmapToggleButton the same but with bitmaps.
