/**
* Specifies the tint value applied to the ctColor.
*
*
* If tint is supplied, then it is applied to the RGB value of the ctColor to determine the final
* ctColor applied.
*
*
* The tint value is stored as a double from -1.0 .. 1.0, where -1.0 means 100% darken and
* 1.0 means 100% lighten. Also, 0.0 means no change.
*
*
* In loading the RGB value, it is converted to HLS where HLS values are (0..HLSMAX), where
* HLSMAX is currently 255.
*
* Here are some examples of how to apply tint to ctColor:
*
*
* If (tint < 0)
* Lum' = Lum * (1.0 + tint)
*
* For example: Lum = 200; tint = -0.5; Darken 50%
* Lum' = 200 * (0.5) => 100
* For example: Lum = 200; tint = -1.0; Darken 100% (make black)
* Lum' = 200 * (1.0-1.0) => 0
* If (tint > 0)
* Lum' = Lum * (1.0-tint) + (HLSMAX - HLSMAX * (1.0-tint))
* For example: Lum = 100; tint = 0.75; Lighten 75%
*
* Lum' = 100 * (1-.75) + (HLSMAX - HLSMAX*(1-.75))
* = 100 * .25 + (255 - 255 * .25)
* = 25 + (255 - 63) = 25 + 192 = 217
* For example: Lum = 100; tint = 1.0; Lighten 100% (make white)
* Lum' = 100 * (1-1) + (HLSMAX - HLSMAX*(1-1))
* = 100 * 0 + (255 - 255 * 0)
