[gentoo-dev] font.eclass add Xorg FontPath elements for non-standard paths

Hello,

as Ondrej Grover pointed out on [1], the font.eclass installs font
files and indexes (font.dir, fonts.scale) into sub-dirs of
/usr/share/fonts/, e.g. /usr/share/fonts/terminus.

These directories are naturally not in the fontpath of Xorg server,
and could not be used without adding these with xset fp+.
As said on the bug, the Xserver itself should be abled to find all
fonts, and it's not the duty of the xinitrc/window-manager to collect
all these paths in the users process.

I'd like to propose a patch to font.eclass to add the newly created
paths to the Xorg server configuration via xorg.conf.d files [2].
I contacted fonts alias and, as mentioned on the bug and irc, Ben de
Groot (yngwin) does not object and says that font team lead Peter
Volkov (pva) is non-active.

Please review for technical problems (esp. for EPREFIX).

Open questions:

- - Should the (current) default xorg server paths
  /usr/share/fonts/{75dpi,100dpi,misc,TTF,OTF,TYPE1} really be excluded?
  How would the startup and font lookup perfomance degrade with
  multiple conf.d files, containing the same path multiple times?

- - How would already installed font packages see this fix?
  Revbump (and stabilize) every one of them?

- - Alternative solutions would be installing fonts in xorg-servers
  default paths or add one configuration file that gets newly
  assembled  on every font_pkg_postinst run.

Thanks
