wxPython Slider Experiment

# experiment with wxPython's wx.Slider
# wx.Slider(parent, id, init_val, min_val, max_val, position_tuple, size_tuple, style)
# position_tuple (x, y) of upper left corner, size_tuple (width, height)
# (on my Windows XP the mouse-wheel controls the slider that has the focus)
# tested with Python24 and wxPython26     vegaseat     17oct2005
