It doesn't make sense to have `Pixels: Mul<Pixels, Output = Pixels>` as the output should be `Pixels^2` (area), so these impls are removed. All code where these impls were used are improved by instead multiplying by `f32` or `usize`. Also adds math op impls that are present for `Pixels` but absent for `ScaledPixels`. Adds missing `Mul<Pixels> for usize` to both. Release Notes: - N/A
