A paint class that creates conical gradients around a given center point
It could be used in the same way as LinearGradientPaint and RadialGradientPaint
and follows the same syntax.
With the START_COLOR at the beginning and the DESTINATION_COLOR at the end of the given RANGE the method will calculate
and return the color that equals the given VALUE.
Returns the color that equals the value from CURRENT_FRACTION in a RANGE of values
where the start of the RANGE equals the SOURCE_COLOR and the end of the RANGE
equals the DESTINATION_COLOR.
Returns the interpolated color that you get if you multiply the delta between
color2 and color1 with the given fraction (for each channel) and interpolation.
