[pdftex] Font Embedding and Font Substitutions

Hi all,

I have a question regarding pdflatex's font embedding and font substitution.
I have a latex file that includes two graphics.  pdffonts returns the
following on each:

name                                 type         emb sub uni object ID
------------------------------------ ------------ --- --- --- ---------
GXJYGS+CMMI10                        Type 1C      yes yes no      11  0
QAKHSM+CMMI7                         Type 1C      yes yes no      13  0

name                                 type         emb sub uni object ID
------------------------------------ ------------ --- --- --- ---------
CPKLQV+CMMI7                         Type 1C      yes yes no      19  0
EKIDYN+CMMI10                        Type 1C      yes yes no      11  0

Then I run pdflatex on my latex file and get an ouput that shows the
following with pdffonts:

name                                 type         emb sub uni object ID
------------------------------------ ------------ --- --- --- ---------
EIOZYT+CMMI10                        Type 1       yes yes no      31  0
PMUOFJ+CMMI7                         Type 1       yes yes no     282  0
EIOZYT+CMMI10                        Type 1       yes yes no     982  0
PMUOFJ+CMMI7                         Type 1       yes yes no     985  0
PMUOFJ+CMMI7                         Type 1       yes yes no    1022  0
EIOZYT+CMMI10                        Type 1       yes yes no    1031  0

So it's great that the CMMI7 and CMMI10 fonts have been consolidated
(note how they all have the same prefix).  However, they still show up
twice in pdffonts.  So what does this mean?  It seems like everything
should have been consolidated to only show up once.

I am using gs 8.54 and epstopdf to create the two images and pdflatex 1.40beta
to generate the final document.

Thanks,
Paarvai
