Asymptote: 2.80 Released

Asymptote https://asymptote.sourceforge.io is a powerful descriptive vector graphics language for technical drawing, inspired by MetaPost but with an improved C++-like syntax. Asymptote provides for figures the same high-quality level of typesetting that LaTeX does for scientific text.

Compression of empty transparent pixel counts and other optimizations were implemented in the transparency shader. A weighted least-squares fit was added.
