[Lazarus] Building FPC/Lazarus from source

[cc_ at freemail.hu]

Not from my head, just googled out stuff:

GTK+ <http://en.wikipedia.org/wiki/GTK%2B>, starting in 2005 with 
version 2.8, uses Cairo to render the majority of its widgets 
<http://en.wikipedia.org/wiki/Widget_%28computing%29>.


Trying to remove libcairo2 causes the removal of everything else, 
including libgtk2 etc. on Hardy Heron (64bit) so at least on linux, I'd 
say it's "part of the system" when considering gtk2 setups.

If the gtk 2.8 comment (from wikipedia) is true, then we should be safe 
to use it on unix platforms at least (we're supporting 2.6+ but I think 
going to 2.8+ as minimum is doable?)
