EFL patch is done ! If EFL needs to do rebaseline after landing EFL patch
[2], let me do it.

> Hello!
> As of r197145, the SVG -> OTF Font Converter is enabled on the OS X, iOS,
> and Apple Windows ports. This converter replaces our old, invasive,
> error-prone, and security-hole-ridden SVG font support in WebKit. The
> converter is much faster (read: at least 3 orders of magnitude) and
> produces much better results (subpixel-antialiased text) than the old code
> path, as well as having significantly fewer security vulnerabilities.
> As soon as we get all the ports on the converter, I’d love to be able to
> delete all the old code. However, GTK and EFL are still using the old code
> path. Turning the converter on should be simple: I’ve posted patches for
> GTK [1] and EFL [2] to flip the switch. Note that some tests may need to be
> rebaselined; the underlying graphics system will likely provide differently
> quantized glyph metrics than the existing code path. There are also some
> known bugs; if you want to learn more about them, please feel free to reach
> out to me.
> Please reply by Tuesday, March 15 so I can go ahead with this project!
> Thanks!
