On a tangent, I need a name for the struct that will represent HSL/HSV/HSI/HCY.
They're all basically identical, and might as well be a parameter to a
shared type... but I can't think of a name for that type! >_<
I can't reasonably call it any of those or it would be confused,
rather, each of those would be an alias for an instantiation of each
type.
I'm thinking along the lines of PolarRGB? It's not really that though.
I can't think of any other good names.
alias HSL = PolarRGB!(Type.HSL);

Naming things is so hard!
