[whatwg] Add EXIF metadata support in Canvas.toBlob?

[Alexandre Morgaut]

We have a JS API for that in Wakanda
http://doc.wakanda.org/Images/Image-Class/meta.303-660131.en.html

It use the saveMeta() meta method to apply potential changes:

It was implemented a bit fast but it does correctly the job for now
