eww: delay/defer image loading

eww: delay/defer image loading

[T. V. Raman]

If I use eww to display rss feeds that are converted to html via
xslt I notice that eww is busily loading lots of urls in the
background -- many of these images.

Example: Cnet Tech News RSS:
http://feeds.feedburner.com/cnet/tcoc

I got a number of these downloads to not happen by temporarily
advising eww-display-image to be a no-op -- could we have a
user-customizable option to defer loading images?

You can inhibit image loading by binding `shr-inhibit-images' to a
non-nil value.  Perhaps that should be a more user-visible variable.

Thanks for the pointer to shr-inhibit-images -- I did find that
eventually.

It might be useful to surface all user customizations for EWW via the
eww- prefix -- and completely hide shr- as an implementation detail.

I'd prefer if they were simply in the same customization group hierarchy.

They're both in the "hypermedia" hierarchy, but perhaps there should be
a "web" sub-hierarchy there where they both could live?

Yes, that would make sense. "Hypermedia" is clearly a term not in wide
use so I would even rename that group to something else.

Geez.  I'll just rename this to 'web.
