I would *love* to see these released as official -

- removed vertical scaling of flat primitives, although that was not really a problem and not worth a hold vote IMHO
- I checked the file visually but could not find any T junction
- I ran the file through DATHeader 3.0.22.0, and it also could not find any T junction

I think the file is fine to go

fixed the overlap. it was a single digit "3" at 1 vertex.

I now also saw the T junctions: they are present wherever a 2-4disc contacts 1 side of an adjacent quad.

however, I see no use in fixing them because this would increase the polygon number in this file,
and this file will be used in thousands of instances within a model, in a very tiny size.
so nobody will notice these T junctions.

I would say to this file in its current state now "good to go!"
