Asymptote is a powerful descriptive vector graphics language for technical drawing, inspired by MetaPost but with an improved C++-like syntax. It provides for figures the same high-quality level of typesetting that LaTeX does for scientific text. Asymptote is a programming language as opposed to just a graphics program. It can exploit the best features of script (command-driven) and graphical user interface (GUI) methods. High-level graphics commands are implemented in the language itself, allowing them to be easily tailored to specific applications. License: GNU General Public License (GPL) Changes: A routine was added for projecting a Label onto a given plane. A new inside function checks if one path is strictly inside another. Optional arrows were added to the slopefield routines. The movie function now generates multipage PDF animations when format="pdf" and global=true. A fit argument was added to support an optional filled bounding box for each movie frame. Casts were added between the hsv structure and pens. In inline latex mode, TeX headers are now output only when needed. An xasy bug was fixed. The sticky bit is no longer set when creating the ~/.asy directory.
