line Trim Fade Range
The LineTrimFadeRange property
The fade range for the trim-start and trim-end points is defined by the {@link PropertyFactory#lineTrimOffset} property. The first element of the array represents the fade range from the trim-start point toward the end of the line, while the second element defines the fade range from the trim-end point toward the beginning of the line. The fade result is achieved by interpolating between {@link PropertyFactory#lineTrimColor} and the color specified by the {@link PropertyFactory#lineColor} or the {@link PropertyFactory#lineGradient} property.
