Re: [whatwg] Features for responsive Web design

This is good point.  Could I just clarify my understanding with an example:

Given a thumbnail image with srcset:
srcset="low.jpg 20w, hi.jpg 40w, huge.jpg 80w"

The webpage may want to have the browser scale the 20w image to say 50px
without the browser deciding that the 40w image is more appropriate?

Perhaps it would be realistic for this case to simply not be supported.

Authors have the alternative option of using an encoding with a lower quality
to reduce the image file size, rather than supplying a low resolution image that
the browser scales up.

Perhaps when the file size is far more important than image quality a single image
would suffice anyway.
