Or, with SVG graphics (which are actually a sort of text format, maybe
barely human-readable) becoming more and more common, you might need
trigonometric functions to check, at least approximately, how much space
some slanted line -- possibly some slanted line of text -- would need.

Yes, and for very long files, one might perhaps want an additional digit
or two in the "percentage" item of the status line.

The more complex the functions, the fewer people can be expected to know
how to use them anyway. Trig, log and exponential are at high-school
level, or at least they were when I was in high school (latin-math
section) forty years ago. I wouldn't expect anyone below college level
to even know what Bessel etc. are really for, even if they've heard the
name, which is already far from certain.

Even "fancy display" of HTML -- switch from "source" display to
"rendering" display by hitting a (mapped) key.
Here though, instead of Vince's patch one could send the text to a
browser, maybe a console-mode one such as Lynx displaying in Vim's (not
gvim's) own console, or else something like ":exe '!seamonkey -url
file:///' . expand('%:p')" or similar (for full generality one would
need to percent-escape spaces and other "special" characters), making
use of the fact that Mozilla browsers will by default use something very
much akin to Vim's client-server facility, passing the URL to an
already-running instance if there is one.
Best regards,
Tony.
