The current version (in SVN) implements at least the following:
* all the shapes (lines, rectangles, polylines, paths, etc.)
* transformations (e.g. transform="rotate(30) translate(50, 20)" property)
* flat fills

What is currently not implemented:
* linear, radial fills (implemented in the next commit)
* line styles (linecap, linejoin etc.)
* included bitmaps
* texts

Some of the problems that will be fixed in next commit:

The SVG paths parser currently doesn't handle arcs, witch were
defined in SVG 1.1 but not in SVG 1.2 (I noticed this in the past,
but while referencing to the SVG 1.2 specification I didn't recall).
If you see strange shapes, or no shape at al, it's 99% because of this.

There is a bug in transformations that makes some shapes appear in the
wrong position (like the tiger sample) or completely outside the drawing canvas.

Opacity (transparency) is not handled correctly.

I noticed this also.  Oddly enough, if you convert the SVG document
by command line to XAR and you open it, the geometry (boundings)
appears correct, but if you import it into an existing document, it will
not be centered into the view.

Maybe there is some wrong value in the generated XAR header, I'll investigate
more into this.
