[tex-live] epstopdf: passing command-line options through to ghostscript (patch)

[Markus Kuhn]

Feature suggestion: could you please add to the epstopdf script at

   http://www.ctan.org/tex-archive/support/epstopdf
   #  2012/05/22 v2.18 (Karl Berry)

a command-line option that allows a user to pass arbitrary commandline
options on to ghostscript?

Reason: Ghostscript provides many parameters that a user might want to
tweak during the EPS->PDF conversion, such as resampling the resolution
or font embedding. Allowing the user access to the ghostscript command
line makes it easy to make such tweaks.

Example usage:

   epstopdf --gsopt='-dPDFSETTINGS=/ebook' file.eps

I've attached a suggested patch that adds a new option --gsopt to
that effect. You can specify --gsopt several time to add more than
one option.

Thanks!

Markus
