Simon Pieters wrote up Kornel's earlier approach to a saner, more
palatable source selection algorithm for <picture> (rather than
copying <video>/<audio>). This approach also has a new wrinkle:
<picture> *requires* an <img> child, and it's the <img> that still
actually displays the image. The <picture> element is just a wrapper
for the <img>+<source> elements, and provides a context for the source
selection algorithm. This makes testing substantially easier, as we
can limit ourselves to testing the source selection algorithm, and
probably makes implementation easier as well.
Can we hide the "controlling" <img> in shadow DOM? And make
HTMLPictureElement the interface that proxies relevant properties/events
to the internal <img>?
Reuse of <img> is a great idea for simpler implementation and testing, but
maybe we don't even need to expose that fact to the authors.
