variable stroke width

Add mechanism for variable stroke width (as in calligraphy)

RAISED
Product:

Description:
SVG needs a way to allow the author to specify a variable stroke width, as in calligraphic strokes. The only way to do this currently is to create a new path (which is how Inkscape "fakes" this).

Here is a very primitive early proposal on how to this:

http://www.schepers.cc/differentstrokes.html
http://svg-whiz.com/experiments.html#variableStrokeWidth

The solution should probably be more elegant and algorithmic, and should allow strokes to have different widths on either side of the central stroke line.

It should also interact well with CSS's border properties:

There is also a recent thread about this on SVG-Dev:

Bulia Byak, an Inkscape implementer, supports the idea of a variable stroke width:
