I had a talk to Chris Lilley last night, and he suggested that the following
solution would work using Opera 5 with the Adobe version 2 beta plugin:

HTML page:

<object data="some.svg" class="navbar" type="image/svg+xml">
 <map><p>some useful alternative</p></map>
</object>

HTML Stylesheet:

.navbar { width:14em ; height: 11em }

User stylesheet (made via the browser's nice interface...)

html { font-size: 48pt !inherit }

Then you make an SVG for your navbar, that is 14x11 (in proportion) and the
base font size is 1em, and it comes out being 14x11 ems (where an em is for a
48pt font).

I hope I have got all the code details right - corrections / further
information welcome

Cheers

  Dear Group,
  Here's a follow-up reply I got from Adobe.  I've never been a fan of frames,
  but this seems like a reasonable approach.  Selecting "larger font" from the
  browser tool bar still wouldn't grow the navigation bar, but having the
  graphics scale independently from the text might not be a bad thing.  It is
  not unlikely that the font on the buttons would be significantly smaller the
  default body text font (which the user controls) -- especially in the case
  of a person with low vision -- so therefore it is only the textual graphic
  which require resizing.  Still, it would be nice if there was a way to set
  the size of SVG object based on the users preferred setting for HTML body
  text.
  Kynn, has any of this recent discussion helped address your objections to
  SVG?  Do you still believe that the proposed "cures" (CSS and/or SVG) are
  worse than the "disease" of graphical text?
  Len, any chance of adding SVG navigation bar examples to your resource page?
  Corey, thanks very much!  Your excellent support is almost enough to make me
  regret some of the nasty things I have said about PDF!

  Subject: RE: Resizing the SVG canvas

  Hello Bruce,
  If the SVG is on an html page, then the size is fixed by the height and
  width of
  the embed or object tags. That's standard html behavior for images, plugins,
  Java applets, etc.
  You could put your navigation bar directly into a navigation frame. Your
  'viewbox' would then be the frame border, but users could resize the frame
  by
  dragging to reveal the enlarged SVG artwork.
  <html>
  <frameset cols="80,*">
  <frame src="navigation.svg" name="nav">
  <frame src="page1.html" name="contentpages">
  </frameset>
  <noframes>
  <body bgcolor="#ffffff">
  <p></p>
  </body>
  </noframes>
  </html>
  Best regards,
  Corey
