Unfortunately, it didn't work.

LaTeX: LaTeX found no preview images
----------------------------------------------------------------------

Unlike the case preamble cache is disabled, the current case does not
use the complex stuff of 
"\nonstopmode\nofiles\PassOptionsToPackage{...}{preview}\AtBeginDocument{...}"
at the pdflatex run generating the actual image.  It runs in a simple
form:

pdflatex -interaction=nonstopmode &prv_primárias FILENAME

The complex stuff has been used already when dumping the customized
format prv_primárias.fmt and, I guess, embedded in that format file.
The output when preview-latex dumps the customized format is:

, which can be obtained by C-c C-p C-f.  The init file prv_primárias.ini
is prepared by preview-latex by the following elisp code in
`preview-cache-preamble':
----------------------------------------------------------------------
      ;; mylatex.ltx expects a file name to follow.  Bad. `.tex'
      ;; in the tools bundle is an empty file.

Perhaps we have to modify this .ini file.
