Hi Trevor,

SVG is available for SignWriting.  The automated polygon tracing has 
been available for a while.

With Adam's latest update, the hand shape refinements have been 
completed.  He hand crafted each palm facing for each hand shape.  I 
will need to rotate, mirror, and reorganize his work before it can be 
used in SignPuddle or the SignWriting Image Server.  A few custom 
scripts will perform this work.

The automated polygon tracing is available in 4 flavors: Line Trace, 
Shadow Trace, Smooth, and Angular.  These are available as part of the 
font reference:

You can see these used in the test area for SignPuddle 1.6:

Use the ColumnMaker button to customize the columns.

Select any of the SVG options and press the "Recreate" button.
