I am talking about `org-toggle-latex-fragment'.  And even if that is
fast, it is very annoying behaviour.  I'd very much like to be able to
toggle individual images.  In a math-heavy document the redisplay of all
formula images of even the current section takes noticable moment.  But
much worse: if I am working on a formula, I usually like to see other
formulas as images.  But they disappear as soon as I switch off the
image of the current formula to debug it.

It is quite hard to even achieve the state where all formulas except the
formula under the point are displayed as image.

And I'd expect `org-toggle-latex-fragment' to do what its name suggests:
to toggle the latex fragment, i.e. to produce the same state after the
second invocation.  Similarly to visibility cycling only a prefix should
act globally, IMO.
