bug#2901: 23.0.92; Emacs SVG icon is of bad quality

[Ulrich Mueller]

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/).
