Recently this behavior was removed. Octave had been using  
"convert" (from imagemagick) to produce alternative formats. This is  
now done using ghostscript. Specifically, when a terminal is specified  
that is not supported/recognized, it is assumed that ghostcript is to  
be used to convert to the specified format. As the cairo terminals are  
not explicitly supported, specifying -pdfcairo produces a ghostscript  
error when using the developers sources.

The pdfcairo and pngcairo terminals could be supported, but are not  
supported at this time.

Petr, what are the benefits of the pdfcairo and pngcairo terminals  
over the pdf and png terminals?
