The default 4x MSAA sample positions are 2/16 (0.125) pixels away from the edges. So maybe go with something a bit smaller, like 0.124?

Don't we still need to track the clip coverage layer so that the scissor will get set during clip replays?

Yeah good point, let me refactor this so I can just make should_render conditional.
