Asymptote: 2.17 released

Asymptote (http://asymptote.sourceforge.net) 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.

A bug with non-square pen function images was fixed. Autoscaled
logarithmic axes were fixed. Offscreen and non-offscreen rendering are now
supported in a single binary (requiring OSMesa version 8), with
settings.offscreen defaulting to false. The media9 LaTeX style file is now
used to embed 3D PRC content instead of movie15. Local 3D coordinates are
now used. PRC Part names are nolonger generated by default. A bug in
bezulate was fixed. A settings.axes3 flag was added to control the
visibility of PRC axes. An efficient 3D routine for drawing many
triangles, with specified vertices and optional normals or vertex colors,
was implemented.
