Part of AUCTeX's preview-latex which replaces LaTeX formulas by their
typeset images.  Not exactly invisibility, but still requires similar
action on search and search&replace so that the user can see what
source text he is actually replacing.

Its code would not be useful for isearch, but I thought it helpful to
point out where I had anchored the advice for this similar task.
