text/html rendering erroneously uses frame-width

[Karl Kleinpaste <karl@jprc.com>]

I use a kinda complicated gnus-buffer-configuration (see bottom) which
gives me both horizontal and vertical window splits.  The rendering of
text/html segments appears to be determining line width on the basis
of (frame-width), which is large, rather than (window-width), which is
much smaller.  The result is a really horridly ugly line-wrapped
display of text/html.

I don't really know if this is a Gnus or W3 issue, but I thought I'd
mention it, since the relevant authors are both accessible here.

A quick look through the w3 sources only finds frame-width uses in
css.el, devices.el, and url.el.  Hm, odd.  Any ideas on fixing this?

Screenshots of mis-behavior can be found in
