Re: pdfcairo terminal; seams between bars in the colorbox

Actually, okular doesn't fully work either.

I'm currently writing a presentation where I'm using pdflatex and I'm
including gnuplot figures. In that context okular shows the bands also.
Maybe pdflatex is also buggy, but if mupdf AND evince AND pdflatex have
this bug, maybe we should try to work around it. gv is still ok.

You can see this for yourself probably. I downloaded this figure that
was generated by gnuplot:

  http://mrcal.secretsauce.net/external/figures/diff/diff-radius0-heatmap-splined-opencv8.pdf

And ran "pdflatex tst.tex" where tst.tex is:

  \documentclass[presentation]{beamer}
  \begin{document}
  \includegraphics[keepaspectratio,width=0.9\textwidth,height=0.7\textheight]{/tmp/diff-radius0-heatmap-splined-opencv8.pdf}
  \end{document}

The result is attached. I see the bands even with okular.
