[webkit-dev] Important missing bits in SVG support

[Andreas Neumann]

Hi all,

I am an active SVG developer and am following Webkit's progress 
regarding SVG for a while. I think it is soon at a state where it can be 
used for many SVG projects - not yet complete and bug free, but already 
usable. I am also happy to see that one can convert SVGs to PDF using 
Webkit - great! Thanks for your great work on the SVG support!

Some of my work can be seen at http://www.carto.net/papers/svg/samples/ 
- note that all examples that run in Opera/Batik/Firefox are standard 
compliant, while some of the older or more complex examples might only 
work in ASV (I am working to fix these as well).

I would like to share a list of missing features with you, that I would 
need to get most of my examples working in Webkit:

* dynamic creation of use elements does not yet work: see 
http://www.carto.net/papers/svg/manipulating_svg_with_dom_ecmascript/create_elements.svg 
(try the dynamic creation for <use/> elements)
* support for pointer-events - this is very important for many of my GUI 
elements as well as mapping projects
* support for SVGLocatable - all of these methods and properties are 
very important for coordinate system calculations and for getting 
bounding boxes: .getBBox(), .getCTM(), .getScreenCTM() (very important), 
.getTransformToElement()
* support for SVGPoint and the .matrixTransform() method

I think if these missing bits above are implemented, many of my examples 
will work and I'll be able to write bug reports on other things. 
Currently, most of my examples aren't functional in Webkit due to the 
missing SVGLocatable and SVGPoint methods/properties.

I would greatly appreciate if you could look into supporting these 
methods in the near future.

Thanks a lot,
Andreas
