Faster PNGs: Exploring Zstandard and LZ4 as Alternatives

Slow read/write times are a known issue with PNGs. This post suggests using newer, open-source, patent-free codecs like Zstandard (from Facebook) or LZ4 as a solution. Zstandard is already used in the Khronos KTX2 GPU texture format, offering significant speed improvements. The author also mentions even faster, simpler codecs like QOI, but these might require changes to image pre-processing.
