[fpc-pascal] Using Cairo lib on Linux without X

[Juha Manninen]

FYI, I got ssh access to a Linux server and tested a program made with
Lazarus CairoCancas with NoGui widgetset.
The machine had Mint Linux and libcairo was installed. X11 was
installed, too, but not running. "ldd" shows libcairo depends on X11.

The program amazingly works! It builds a PDF file with Unicode text in
different languages.
The program can be found in lazarus/components/cairocanvas/examples in
case somebody wants to try it.
