There are two ways to do pre-multiplication of the alpha channel into the color channels: on optical values or on electrical values. While pre-multiplication with optical values is arguably more correct, because operations like blending or scaling require pre-multiplied, optical color channels, wayland and compositors by default work with pre-multiplied electrical values. This is most likely a convention that Wayland took from Cairo. This commit makes sure that the expectation of pre-multiplied electrical values is properly documented.
