Apply the function f to each channel except the alpha channel. Apply the function g to the alpha channel.

fn map2<F>(&self, other: &Self, f: F) -> Self where
    F: Fn(Self::Subpixel, Self::Subpixel) -> Self::Subpixel, 

Apply the function f to each channel of this pixel and other pairwise.

fn apply2<F>(&mut self, other: &Self, f: F) where
    F: Fn(Self::Subpixel, Self::Subpixel) -> Self::Subpixel, 

Apply the function f to each channel of this pixel and other pairwise. Works in-place.
