Make cx, cy default to 0

[stuaxo]

Fixed to match the spec at

https://developer.mozilla.org/en-US/docs/Web/SVG/Attribute/cx

https://developer.mozilla.org/en-US/docs/Web/SVG/Attribute/cy

Means it can load the wikipedia smiley, though rendering is not correct yet

There are some things that don't display yet:

The right eye - this seems to be the 'use' tag not working.the gradient effect seems to be 'radialGradient' which is not implemented yet.

Possibly the problem with the right eye is something to do with the way they use 'scale(-1, 1)' to draw features on the right side.

Thanks, I got the smiley working in my latest commit. A few things were going on, the use directive wasn't being processed correctly, and as you noticed cx/cy wasn't being initialized. It also wasn't using fx/fy, which it does now, although I need to make it process focal points more correctly.

Awesome, seems to run very well, and with it's radialGradient :)

Guess I need to make this use it now

Not sure if it's worth adding the svg to the svgs, if licensing permits as it, as it has a couple of tricky things inside ?
