Asymptote: 2.81 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.

Schur decompositions were implemented. A bug in uniform() was fixed. The Xasy bounding box and a crash when opening Xasy files were fixed. The transparency offset buffer is zeroed when GPU compression is unavailable. The surface constructor for solids of revolution was documented. Support for pkg-config was added. Opaque rendering on platforms lacking GL_ARB_fragment_shader_interlock was fixed.
