Ahan Wu 4c9a55087b Using linear interpolation in fragment shader to avoid over saturation. ...

fragment shader so we also apply linear interpolation between original
color and remapped color to avoid over saturation.

In addition, we also add some comments, which is offered by UX,
to fragment shader, thanks the great help of Vignesh!
