*** doc-view can now generate SVG images when viewing PDF files.
If Emacs is built with SVG support, doc-view can generate SVG files
when using MuPDF as the converter for PDF files, which generally leads
to sharper images (especially when zooming), and allows customization
of background and foreground color of the page via the new user
options 'doc-view-svg-background' and 'doc-view-svg-foreground'. To
activate this behaviour, set 'doc-view-mupdf-use-svg' to non-nil if
your Emacs has SVG support. Note that, with some versions of MuPDF,
SVG generation is known to sometimes produce SVG files that are buggy
or can take a long time to render.
