Original change's description:
> Evenly space gradient stage.

> Numbers from Skylake...
> Before:
> ./out/Release/nanobench --config srgb \
> --match gradient_linear_clamp_3color gradient_linear_clamp_hicolor -q 19:48:13
> Timer overhead: 36.7ns
> ! -> high variance, ? -> moderate variance
> micros bench
> 439.92 ? gradient_linear_clamp_3color srgb
> 2697.60 gradient_linear_clamp_hicolor srgb
> 437.28 gradient_linear_clamp_3color_4f srgb
> 2700.50 gradient_linear_clamp_hicolor_4f srgb
>
>
> After:
> micros bench
> 382.35 gradient_linear_clamp_3color srgb
> 593.49 gradient_linear_clamp_hicolor srgb
> 382.36 gradient_linear_clamp_3color_4f srgb
> 565.60 gradient_linear_clamp_hicolor_4f srgb

> Numbers on my Mac Trashcan are about even; there is no
> speedup or slowdown between master and this change.
