While getting the required stuff for OpenSuse Tumbleweed, I noticed
a problem with the current toolchain, that affects both html and
PDF:

/usr/bin/dot -Tpdf /home/mchehab/docs/Documentation/doc-guide/hello.dot
Format: "pdf" not recognized. Use one of: canon cmap cmapx cmapx_np dot eps fig gv imap imap_np ismap pic plain plain-ext pov ps ps2 svg svgz tk vml vmlz xdot xdot1.2 xdot1.4

$ ls -lctra  Documentation/output/doc-guide/latex/hello.pdf
-rw-rw-r-- 1 mchehab mchehab 0 jul 15 16:20 Documentation/output/doc-guide/latex/hello.pdf

Btw, the same error is happening also with Fedora 26. So, I guess kfigure 
should test if pdf is supported, otherwise convert to some other format
(like ps or svg).

E. g. calling it with something like:

	$ dot -T help
	Format: "help" not recognized. Use one of: canon cmap cmapx cmapx_np dot eps fig gv imap imap_np ismap pic plain plain-ext pov ps ps2 svg svgz tk vml vmlz xdot xdot1.2 xdot1.4

then parse its output, before assuming that the requested format is
available.


Thanks,
Mauro
