wxScrolledPanel fills a "hole" in the implementation of wxScrolledWindow,
providing automatic scrollbar and scrolling behavior and the tab traversal
mangement that wxScrolledWindow lacks. This code was based on the original
management that wxScrolledWindow lacks. This code was based on the original
demo code showing how to do this, but is now available for general use
as a proper class (and the demo is now converted to just use it.)

This module defines a Logger class, responsible for managing
debugging output. Each Logger instance can be given a name
at construction; if this is done, '<name>:' will precede each
logging output made by that Logger instance.
The log() function this class provides takes a set of positional
arguments that are printed in order if debugging is enabled
(just like print does), followed by a set of keyword arguments
that control the behavior of the dbg() function itself on subsequent

You can also call the log function implicitly on the Logger
instance, ie. you can type:
from wxPython.tools.dbg import Logger
dbg = Logger()
dbg('something to print')
Using this fairly simple mechanism, it is possible to get fairly
useful debugging output in a program. Consider the following
code example:
>>> d = {1:'a', 2:'dictionary', 3:'of', 4:'words'}
>>> logger = dbg.Logger()
>>> dbg = logger.dbg
>>> dbg = dbg.Logger('module')
>>> dbg(enable=1)
