Make sure RGB list is converted to RGBA

[cymplecy]

What's the most Snap!pish way to ensure that RGB / RGBA lists always end up as RGBA lists?

I can do it industrially like this

but feel there should be a better way

I've come up with this so far

What's wrong with the simplest

or

normalized (rgb)A

For a very large pixel array, "columns" may be faster than "map" of every element.

Sorry - I just need it for the simple 1 pixel list of values - not needing to map over a list of pixels

As performance is a non-issue, the question is, whatever you find a more Snap!pish ...
