Insane(ly slow but wicked good) PNG image optimization

JPEG XL image format reference implementation

Merged into Gifsicle!

Go package to simulate bandwidth, latency and packet loss for net.PacketConn and net.Conn interfaces

Lossy PNG compressor for RGBA PNGs. Has two modes: lossy averaging filter (blurizer) that denoises the image and optimal posterization using Median Cut quantization to reduce number of unique colors in the image with minimal visual distortion
