I really think it would be valuable to be able to spec an unzoomable font
size.  Here is a use case -

I lay out and label a graph and I determine that I want 10 pt font for some
good reason like esthetics or readability.  It is hard enough to get the
size I want when I use teh page viewport to scale the numbers, but suppose I
have done that.  Now I find that my graph does not fit the page as well as I
want, and I wish to resize it.  I definitely want to resize the graph while
leaving the font in 10 pt.

I realize that it is not obvious how do know when to allow something to
scale and when not to, and there are plenty of cases where you would want to
scale the entir drawing, fonts and all.  But type is a special case, and it
ought to be possible to say what font size you want and by Jove to get it.

 Lots of work, but it would be nice ...
