I was very pleased to notice that my small Xlib-utility xdraw has made it across the years unscathed. It compiled after 11 years of complete lack of code or build system maintenance. Hail to the stability of the X Library!

However, i found the visual quality of the drawing results a bit lacking – the drawn lines are too uneasy. So i have added weighted average smoothing to the drawn lines.

I have released this improvement as version 1.1 of xdraw here: https://gitlab.tk-sls.de/tilman/xdraw/tree/1.1
