preview-latex <URL:http://www.gnu.org/software/auctex/preview-latex>
extensively uses overlays (and they can easily grow to a few thousand
per document in a mathematically oriented paper), and it is very clearly
_overlays_ which are wanted here since the associated images are only
correct in the context and position of a particular document and would
not make any sense at all to copy and paste.
Quadratic behavior for the markers used as start- and end markers is
clearly undesirable.
Naturally, this could be addressed by changing the data
structures/algorithms for updating markers (thus killing two birds with
one stone). But whether solved together with marker behavior or not,
this is worth addressing.
