yes, every row of pixels is stretched to 4 pixels here, for the sake of convenience, and also giving some leeway to artists. Otherwise, texture filtering might cause inter-row bleed which could turn blinking into wandering. I do want to use linear filtering to smooth out the motion, though. The shader has a parameter to apply a harden the threshold to make blinking more snappy. I'm really happy with the result!
