I have a challenge for you graphics peeps. Let's have a thread about it. I'm emulating a GPU that can draw points, lines, triangles, and quads. All are specified with four points, but some are coincident for lower-order shapes. There is no guaranteed order for the points. [1/?]
I've gotten as far as sorting by Y and calculating coincident points. In general it feels like rejecting coincident points should come first, since it makes the Y-sort more efficient. But it's mainly the "determining vertex ordering" part that is a bit fiddly for me at the moment

checking for coincident points is easier once they are sorted by Y, but sure

point ordering doesn’t matter so much once sorted. pick the next two (unique) points, the smaller value will be the left edge, etc
