I'd like to adopt and upgrade libwebp to date as it is now up to 1.2.2 
from 0.6.1 and available and supported in most distros and all browsers 
   (including our Qupzilla) except (unsupported) IE and older packages:

	https://cygwin.com/packages/summary/libwebp-src.html

The cygport is available in the libwebp package git repo playground branch:

https://cygwin.com/git/?p=git/cygwin-packages/libwebp.git;f=libwebp.cygport;hb=refs/heads/playground

and the packages have been built under scallywag:

	https://cygwin.com/cgi-bin2/jobs.cgi?srcpkg=libwebp

logs in:

	https://github.com/cygwin/scallywag/actions/runs/1771264878

I picked up the package because I thought our images at
cygwin-htdocs/goldstars/img/ seemed large for small icons:

$ wc -c img/*
   3473 img/dungbomb.png
   1074 img/goldstar.png
   1303 img/goldwatch.png
   9382 img/pinkwatch.jpg
    877 img/platinumwatch.jpg
    878 img/plush_hippo.jpg
   1055 img/silverstar.png
18042 total

so converted them and found they were much smaller in webp format, and 
reconverting using the upgraded package command:

	$ cwebp -blend_alpha 0xffffff img/$img -o images/$i.webp

$ wc -c images/*
   220 images/dungbomb.webp
   284 images/goldstar.webp
   286 images/goldwatch.webp
   322 images/pinkwatch.webp
   232 images/platinumwatch.webp
   204 images/plush_hippo.webp
   174 images/silverstar.webp
1722 total

Those images are attached if anyone wants to standardize the images in 
the directory and update the img src file types in goldstars/index.html.

Conversion of all cygwin-htdocs web site images to webp (including using 
`gif2webp -mixed` and converting X2.bmp to png then webp) would reduce 
the total image sizes from 907008 to 236842: details are attached.
Updating these would make the site more mobile friendly, quicker for 
those on low-bandwidth connections, and cheaper for those on expensive 
plans.
