ABU 31-dec-2021 (ver 1.0 released)
ABU 4-jan-2021 - Thanks to everybody for their suggestions. (minor) Bug-fixing is in progress; please append your comments in the Discussion section below
Everything started with a little experiment, trying to draw splines (Catmull-Rom Centripetal Splines), but then ... why not a full editor ?
Well, this is not a full professional editor, it's just the 1.0 milestone but I think it has enough features for creating interesting vectorial drawings.
Here you can download the full source ( it's 100% pure Tcl )
