ColourPickerSlider class

A single-axis colour slider for one channel of a colour model.

Renders a gradient track appropriate for the given trackType (hue, saturation, value, lightness, red, green, blue, or alpha) and a draggable thumb that reports colour changes through onColorChanged.

The track gradient updates to reflect the current hsvColor, so each slider always shows the range of values that are available given the other channels' current settings.

Set displayThumbColor to true to fill the thumb with the colour it represents, or leave it false for a plain white thumb.
