[Bug-AUCTeX] dvipng transparency and eps

[Kasper Peeters]

Hi,

When using the "-bg Transparent" option to dvipng, any EPS figures
which are included using \includegraphics still keep their
nontransparent background. I tried replacing the 

    char *device="-sDEVICE=png16m";

line in special.c with 

    char *device="-sDEVICE=pngalpha";

to make sure that ghostscript spits out images with an alpha channel,
but this didn't work (if the eps is run through ghostscript
separately, the pngalpha device _does_ produce an image with alpha
channel, so it seems to be a problem inside dvipng).
