How can I render pixel art images with no AA and transparent background?

Question

My question is: How can I render a pixel art image with cycles (low resolution) which is ready for use in a game? That means: no border antialiasing, a transparent background, and a real 1:1 pixel ratio (no scaled image) in the end result.

I've already found a few related questions, but none completely answers my question. The closest I've got is this (more or less copied from here): The problem is that it still has a white background, which I don't want. When I change the alpha channel of the color in the upper input of the "Mix" node, the whole image gets more transparent, which is not intended, of course.

Instead of Mix node use Set Alpha node:

Great, exactly what I wanted! Still adjustable and everything… But why did the alpha channel of one mix node input affect the whole image? – Ignatiamus Oct 03 '18 at 15:12
I don't know. For mixing images with alpha use alpha over node. – Crantisz Oct 03 '18 at 15:34
