What feature would you like to be added?

Usually when I deal with ColorScale in the engine, I'd like to change the color to be exactly as my desired color.Color.

Would it be possible to add

func (c *ColorScale) Set(r, g, b, a float32) {
	c.r_1 = r - 1
	c.g_1 = g - 1
	c.b_1 = b - 1
	c.a_1 = a - 1
}

and/or

func (c *ColorScale) SetWithColor(clr color.Color) {
	cr, cg, cb, ca := clr.RGBA()
	c.Set(float32(cr)/0xffff, float32(cg)/0xffff, float32(cb)/0xffff, float32(ca)/0xffff)
}

functions?

Why is this needed?

ease of use, instead of calling SetR/SetG/SetB/SetA separately

Sure, Set and SetWithColor seem fine.

By the way, you can do the same thing with Reset and Scale now:

func (c *ColorScale) Set(r, g, b, a float32) {
    c.Reset()
    c.Scale(r, g, b, a)
}

func (c *ColorScale) SetWithColor(clr color.Color) {
    c.Reset()
    c.ScaleWithColor(clr)
}
