Comment 13 for bug 168261

A note on perspective and intrinsic sizing, I just wanted to leave a quick
pointer to bug 70978 (and maybe bug 70976). That is to say, it would be (more
than) nice for the ability to include an SVG graphic, say only specifying an 80%
width, and have the height automatically scaled to maintain the image's
intrinsic perspective. If I want to include an SVG banner for a website that
will scale properly when displayed on a 2" Cell Phone screen or 20" Desktop LCD
- I can specify a width of 80% of the page, but there is then no way to specify
a height that will maintain the image's perspective. Em's could be used, but
that's a less than ideal workaround.
