The HSBInterpolator class provides Hue, Saturation, and Brightness (HSB) color interpolation between RGB uint start and end values. Interpolation is done by treating the start and end values as integers with RGB color channel information in the least-significant 3 bytes, converting these to HSB values, and interpolating linearly for each of the h (hue), s (saturation), and b (brightness) parameters.

Because this interpolator may perform more calculations than a typical interpolator that is simply interpolating a given type, specifically to convert the RGB start and end values, this interpolator provides the option of supplying start and end values to the constructor. If you specify the start and end RGB values, then the conversions of these values is calculated once, and does not need to be done at every future call to the interpolate() method during the animation.

	`startRGB:uint` (default = `NaN`) — The starting color, as an unsigned integer RGB value.

	`endRGB:uint` (default = `NaN`) — The ending color, as an unsigned integer RGB value.

	`baseValue:Object` — The start value of the interpolation.

	`decrementValue:Object` — The change to apply to the `baseValue`.

	`baseValue:Object` — The start value of the interpolation.

	`incrementValue:Object` — The change to apply to the `baseValue`.

	`fraction:Number` — The fraction elapsed of the animation, between 0.0 and 1.0.

	`startValue:Object` — The start value of the interpolation.

	`endValue:Object` — The end value of the interpolation.
