PGM Raw in sintesi

PGM Raw

The raw PGM branch reflects the practical evolution of Netpbm-style tool formats: keep the tiny header and easy parsing, but move the pixel raster into a binary form that is much more usable for real data sizes.

JXR in sintesi

JXR

JPEG XR grew from Microsoft's HD Photo work and then moved through standards bodies, but it remained much more niche than formats such as JPEG, PNG, or later AVIF/WebP families.
