I have uploaded a new version of 'draw' to
http://www.telefonica.net/web2/biomates/maxima/gpdraw/
The most important changes are:
1. Renamed functions and global variable: draw2d, draw3d, draw and
draw_pipes.
2. Implicit plot routine, kindly written and sent to me by Andrej
Vodopivec.
3. Three new examples in the html document: including a topological 3d
animation, as suggested by Laurent and Nicolas.

PD: I'll commit this package to the contrib section this week.
