Color.Gradient.linearGradient with size 1 results in NaN

[Widdershin]

Hello,

I've encountered an issue with the linearGradient function.

> import Color exposing (Color)
> import Color.Interpolate exposing (..)
> import Color.Gradient exposing (linearGradient)
> palette = [ Color.white, Color.white ]
> linearGradient RGB palette 1
[RGBA NaN NaN NaN NaN] : Color.Gradient.Palette

In this case, I feel like we should get a palette back that simply consists of white, rather than NaN.

Perhaps this is related to https://github.com/elm-lang/core/issues/895 but I have not done enough digging to find the root cause.

Yes its related. I don't think this should be fix here.
