Hi Robin,

Thanks for the response.

Should we any of this in the window modes spec (e.g. in the examples
section)?

I can agree that this may have been discussed elsewhere as a general
concept for the web but I see this as having more relevance to widgets
and mobile web apps specifically. The type of scaling we're talking
about is not changing the look and feel (e.g. no proxy/content
transformation) but maintaining all proportions of the developed widget
and just changing the resolution at which it displays. Perhaps there's a
specific term for this: uniform scaling, perhaps? The concept of scaling
is largely fuzzy so it's good to document exactly what type of scaling
is on the table. 

So, uniform scaling is not content transformation or content adapation.
Adaption can be rightly left to CSS.

This ability for my browser to normalize whatever has been produced for
different resolutions on to my handheld screen is likely to be useful,
if not critical, for widget UX (think iphone webapps, for example, that
always fit to screen - albeit one screen size - through a combination of
viewport (i.e. proportionate scaling) and good CSS toolkits (i.e.
elastic css concepts)).

I'm unclear if we should follow-up on this or pass it over to another WG
- like the CSS WG (with the emphasis of this concept on mobile widgets)
but I'm interested on anyone's further thoughts.

Still a few open questions there that may be worth exploring a bit.
