Asymptote 1.33

Asymptote is a powerful script-based vector graphics language that provides a natural coordinate-based framework for technical drawing.
Asymptote has labels and equations that are typeset with LaTeX, for high-quality PostScript output.
A major advantage of Asymptote over other graphics packages is that it is a programming language, as opposed to just a graphics program: it can therefore exploit the best features of script (command-driven) and graphical user interface (GUI) methods.
Main features:
- inspired by MetaPost, with much cleaner, powerful C++-like programming syntax and numerics;
- mathematically oriented (e.g. rotation of vectors by complex multiplication);
- LaTeX typesetting of labels (important for document consistency);
- compiles figures into virtual machine code for speed without sacrificing portability;
- uses simplex method and deferred drawing to solve overall size constraint issues between fixed-sized objects (labels and arrowheads) and objects that should scale with figure size;
- high-level graphics commands are implemented in the Asymptote language itself, allowing them to be easily tailored to specific applications;
- provides a standard for typesetting mathematical figures, just as TeX/LaTeX has become the standard for typesetting equations.
Enhancements:
Routines to find the 3D and projected 2D bounding boxes of Bezier surfaces
were added to the surface module, along with the standard teapot example.
Extended for loops were documented. The page numbering of slide
presentations with stepping enabled was fixed. The int type is now a long
long type (typically a 64-bit integer). Support for reading and writing
64-bit integers in binary and XDR modes and large file support were added.
Input files are now opened in input-only mode. Multiple invocations
of labelpath now work. A projection bug in the grid3 module was fixed.
The search path order was changed: directories specified by the dir
configuration variable are now examined before the .asy subdirectory in the
users home directory. User configuration files are ignored during
installation. Some bugs in asy-mode.el were fixed. Texput files are
removed again. A memory allocation incompatibility in the workaround for
old, broken readline libraries was fixed. The framepoint and truepoint
routines now work even when an exact picture size estimate is unavailable;
a picture scaling bug was fixed. Writing to a file specified with
-o /dir/file.eps is allowed again. A quarticroots solver was added, the
cubicroots solver was improved, and a complex quadraticroots solver was
added. A workaround for broken texi2dvi installations was implemented.
Memory leaks were fixed. The garbage collector was update to gc-7.0;
upgrading to gv-3.6.3 is also recommended. A segmentation fault in
complement was fixed.
