           Summary: WebKit lacks support for "defer" keyword on

WebKit lacks support for "defer" keyword on preserveAspectRatio

>From the spec:

http://www.w3.org/TR/SVG/coords.html#PreserveAspectRatioAttribute
If the value of preserveAspectRatio on an 'image' element starts with 'defer'
then the value of the preserveAspectRatio attribute on the referenced content
if present should be used.  If the referenced content lacks a value for
preserveAspectRatio then the preserveAspectRatio attribute should be processed
as normal (ignoring 'defer').  For preserveAspectRatio on all other elements
the 'defer' portion of the attribute is ignored.

This seems to be a very obscure corner of the spec.  Support here will depend
on actually having support for <image> tags which reference SVG files.  It
seems marking a preserveAspectRatio on an <image> as 'defer' means, that the
implementation is supposed to parse the preserveAspectRatio out of the .svg
file and use it in the context of the <image>.
