A Pure-Python Colour Slider

The colour slider displays transitions from value 0 to value 1 in HSV, allowing the user to select a colour within the transition spectrum.

This class is best accompanying by a wxSlider that allows the user to select a particular colour shade.

Method Summary
	`__init__(self, parent, id, colour)` Creates a blank slider instance.
	`DrawBuffer(self)` Actual implementation of the widget's drawing.
	`GetBaseColour(self)` Return the current colour used as a colour base for filling out the slider.
	`GetValue(self, pos)` Returns the colour value for a position on the slider.
	`SetBaseColour(self, colour)` Sets the base, or target colour, to use as the central colour when calculating colour transitions.
