It is possible to quickly (that is, without going through a decode-modify-encode pipeline) compute neighbours of a Morton-encoded coordinate. The technique is mentioned on [wikipedia](https://en.wikipedia.org/wiki/Z-order_curve#Coordinate_values). That could be useful to...

If I call this as it is, for example `LLVM.DIBuilderCreateBasicType(dibuilder, "i32", 32, 32, 5)`, and then do DumpModule, I can see that the string has become 32 characters long and...

Vectorized Paeth filtering (multiple pixels at the same time)

Most PNG decoders (including the one in Wuffs from what I can see) use a pixel-by-pixel approach to filtering, and may use SIMD for parallelism across the channels of a...

Vectorized Paeth filtering (multiple pixels at the same time)

I've seen the other issue about vectorized Paeth filtering, this is not that. It's possible to apply the Paeth filter to multiple pixels at once. Not on 4 sequential pixels,...
