Ah, I see now.  Obviously I read only part of the discussion.  Sorry.

The problem is that both html-resolution and html-scale get translated  
into a pixel size.
what we really would need is to make the picture big and the to scale  
it down in the browser
by an html attribute.  Maybe :html-scale is an unfortunate naming  
because it it sounds like
it would be an html attribute for the included image.

Did you follow the recent discussion about MathJax?  I think this  
might be a better way
to get good resolution math into an HTML page.

If you want to print the result, why don't you go through LaTeX?
