Stefan Eßer fb16dfecae Remove WWW entries moved into port Makefiles
Commit b7f05445c0 has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.

This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.

This tool computes (dis)similarity between two or more PNG images
using an algorithm approximating human vision.
Comparison is done in L*a*b* color space (D65 white point, sRGB gamma)
using a multi-scale variant of the SSIM algorithm.
Features:
- Improved algorithm
- Compares at multiple weighed resolutions, and scaling is done in
linear-light RGB. It's sensitive to distortions of various sizes
and blends colors correctly to detect e.g. chroma subsampling errors.
- Uses L*a*b* color space for the SSIM algorithm. It measures
brightness and color much better than metrics from average of
RGB channels.
- Supports alpha channel.
- Supports images with color profiles.
- Takes advantage of multi-core CPUs.
- Can be used as a library in C, Rust, and WASM.
- No OpenCV or MATLAB needed.
