I attached two eps files and the pdf generated in latex (tex -> dvi -> pdf) with both eps included.

Both figures look very similar, but if you do a zoom you will see that the numbers in Fig 2 are not jagged as in Fig 1.

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



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


  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).
