C-h C-k [Menueintrag anklicken]
(in CVS Emacs, C-h K)

`C-c C-p C-f'
`preview-dump-format'
LaTeX/Preview/Cache preamble
     Dump a pregenerated format file.  For the rest of the session,
     this file is used when running on the same master file.  Use this
     if you know your LaTeX takes a long time to start up, the speedup
     will be most noticable when generating single or few previews. If
     you change your preamble, do this again.

`C-c C-p C-c C-f'
`preview-clear-format'
LaTeX/Preview/Cache preamble off
     Clear the pregenerated format file. If the above gives you
     problems, use this.

M-x report-emacs-bug RET
The scroll behavior of Emacs is not under control of preview-latex.
If enough people complain, this might shift priorities.

HAHAHAHAHAHAHA.  Good one.  Why do you select unreadably small fonts
in the first place?  Previews get the size the rest of your buffer
gets.

This one is quite probably never going to make it because
a) it necessitates rendering at several resolutions, further slowing
down things
b) tracking moves over images is unfeasible under current versions of
Emacs
c) the usefulness is dubious to me

Notice that the quality of the antialiasing might improve with later
versions of GhostScript, so installing some 7.xx versions might
lessen your desire for this functionality.
