That's what Visuwesh's advice of setting doc-view-svg-face's
foreground/background to black and white would do. We could do that by
default instead of inheriting from the default face (which is modified
by the theme). That would probably give sensible results in most cases.
I've also tried un-inheriting doc-view-svg-face from the default face so
that it is the empty face, i.e., all its attributes are nil. In that
case, it looks exactly as if it inherited from the default face, i.e.,
the document is styled according to the theme with the same problems for
certain files as you see.
I've also created a PDF with blue background and different text colors.
In that case, doc-view-svg-face set to "black on wide" doesn't seem to
have any effect. The foreground/background colors of the document
appear exactly as I've specified them in the original LaTeX document and
as the Evince or mupdf PDF viewer show them, too.
Eli, what do you think?

It seems so.
