Hi.

I would like to ask for changing the line 77 at:

https://hg.savannah.gnu.org/hgweb/octave/file/4e30fd192118/scripts/plot/util/private/__ghostscript__.m#l77

from


  gs_opts = ["-dQUIET -dNOPAUSE -dBATCH -dSAFER -dAutoRotatePages=/None
-sDEVICE=" opts.device];


to


  gs_opts = ["-dQUIET -dNOCACHE -dNOPAUSE -dBATCH -dSAFER
-dAutoRotatePages=/None -sDEVICE=" opts.device];



The reason for this, IIUC, is that the option NOCACHE will prevent gs to
raster fonts.
With this, the generated ps/eps will have better looking fonts when converted
to pdf or inserted in LaTeX files (eps case).

I performed some tests and, indeed, the NOCACHE produced better looking files
in these cases (converting to pdf and inserting the eps into tex).
