Hi Sean,

I'm sorry I wasn't able to join this weeks' call. Is this proposal just
for Web-delivered images, or also for general software images (e.g. the
images on the toolbar of an office suite)?

Separate from that question, I'm concerned about the language below
implying that an image is a bitmap rather than a vector image (e.g.
SVG). Rather than "provided with at least four times the ...
resolution", I wonder if we could just focus on being displayable at at
least 400% of default size without objectionable artifacts, irrespective
of the technique used to accomplish that.

Also, how do we define "objectionable"?
