configure: pdflib, pdf

[Petr M. <mi...@ph...>]

Currently ./configure says at the end:

   jpeg terminal: yes
   gif terminal: yes (with animated gif)
   png terminal: yes
     (jpeg, gif and png terminals can use TTF fonts)
   pdf terminal: no (requires libpdf)
   ... linux, vgagl, ggi, ...
   cairo-based pdf and png terminals: yes

I propose to change the last sentence to
   pdf and png terminals based on cairo: yes
and move it above below the pdf terminal.

Actually, is the pdflib still supported? It seems that this library is 
commercial, so are there any gnuplot users?


I would propose this ordering:

Standalone terminals: yes (always builtin)
...
dot-matrix terminals: no
...
Other file terminals:
   jpeg terminal: yes
   gif terminal: yes (with animated gif)
   png terminal: yes
     (jpeg, gif and png terminals can use TTF fonts)
   pdf terminal: no (requires libpdf)
   ... linux, vgagl, ggi, ...
   pdf and png terminals based on cairo: yes
   lua/tikz ...

Screen terminals:
   ...

(and then maybe Other terminals if there are some remaining).
