The SVG icon in etc/images/icons/hicolor/scalable/apps/emacs.svg
consists entirely (except for the pen) of embedded bitmaps instead of
vectorized paths.

This is against the idea of SVG. It also leads to a ridiculously large
file size, and shows as jagged lines at larger sizes.

Revision 1.1 of the file in CVS was somewhat better (but doesn't pass
SVG validation at http://validator.w3.org/).

You're right, having this particular icon in svg form does seem pretty
stupid... [The same is true of the other SVG emacs icon,
.../mimetypes/emacs-document.svg]

Yeah, the older version seems to be a true scalable SVG file; does
anyone know why it was replaced?

Loading the older (CVS 1.1) svg file into inkscape, and then saving it
(with "save-as") again, _increases_ the number of validation errors on
that website, but seems makes the file more palatable to some apps --
e.g., emacs (and gnome"eog") will load the re-saved file, but not the
original...

Perhaps the older file in "re-saved" form would be better than the
current non-scalable form?

I've replaced the bitmaps in emacs.svg and emacs-document.svg with
(hand-rolled) vector graphics.  The file sizes are now 14K and 12K
respectively, and the svg passes the w3c validator.
