most notably: uses gecko (firefox or mozilla) to render HTML

pkgsrc change: The search path for gtk-doc books has changed. Now
we support the gtk-doc standard share/gtk-doc/html/* (which was patched
out previously), and in addition share/doc/* (which is used by most
pkgsrc installed books). The latter was share/doc/html/* previously
which rendered the whole thing almost useless because only few pkgs
used it. This is in response to PR pkg/34159 by "khorben@syn.localhost".
