Summary

Request to support animation of the viewBox attribute of an svg element. View the above URL in Opera 9.5 (there is a bug but you can see the desired effect) or IE with the Adobe SVG plugin. Minimal test case to be attached

SVG file showing requested behavior Open attachment and click on the red circle. A zooming effect should be created because the viewBox is animated via script. Repeated click result in continual zooming. Works in IE/ASV and Opera(has a hiccup).

Great patch, r=me.
> Source/WebCore/svg/SVGAnimatedRect.cpp:36 > + OwnPtr<SVGAnimatedType> animatedType = SVGAnimatedType::createRect(new FloatRect());
you can omit the braces after the new FloatRect.
> Source/WebCore/svg/SVGAnimatedRect.cpp:75 > + newRect = percentage < 0.5f ? fromRect : toRect;
Again the .f, we don't need that anymore - the style guide says we should omit this.
> Source/WebCore/svg/SVGAnimatedRect.cpp:99 > + return -1;
Does this affect a specific animation mode which won't work with rects?
> Source/WebCore/svg/SVGAnimatedType.cpp:129 > + return String::number(m_data.rect->x()) + ' ' + String::number(m_data.rect->y()) + ' ' > + + String::number(m_data.rect->width()) + ' ' + String::number(m_data.rect->height());
Great, that's exactly how we can construct strings like this efficiently with the new StringAppend operator+ trickery :-)

Really? I asked for it on your other reviews, but you never answered to the question. I was not aware of this change. Just thought this is the case for round numbers like 0 or 1. Isn't it a double if you omit the .f?

Yes, paced animations. Just supported by Opera so far. The specification is vague about that.

Hehe. I know. You told me to use it that way before ;) Thanks for the review.
