bug#17414: 24.3.50; eww ignores scaled text

[Óscar Fuentes]

After visiting a web page with eww and scaling the text
(text-scale-adjust, bound to C-x +) lines wrap. This seems to indicate
that eww organizes the lines of text when it renders the page without
noticing that the buffer's default face was scaled. Reloading the page
(or visiting another page) on the same eww buffer does not change the
parameters eww uses for rendering the text, as if there was no text
scaling.

The only way I know to increase font size on eww without messing up the
page layout is to split the window side-by-side (C-x 3), visit the page
with eww, unsplit the window (C-x 0) and then increase the font size
(C-x +).
