I've been researching our current bundled fonts and think its time to do some
cleanup.

Step 1 - Removals
=================
The current font bundle takes up 42.5 MB and 45% (19.2 MB) of it is taken up by
the Linux Biolinum G, Linux Libertine Display G, and Linux Libertine G fonts
and think they should be the first to go as they takes up way to much space,
they arent highly used fonts, and Khaled Hosney mentioned that "they are
unmaintained, and of limited value if we move to have OpenType features
everywhere."

The next thing on the chopping block would be the second largest font
collection that takes up 22% (9.2 MB), Deja Vu. This Bitstream Vera derivative
which has been around since OOo 2.4 is still being updated, but only has had 5
revisions since LO was created and has limited language support (Latin, Greek,
Cyrillic, Armenian, Georgian). If letting go complete of Deja Vu isnt agreed
upon, then I'd suggest we reduce its size by 45% (to 5.1 MB) by removing the
Condensed and ExtraLight versions.

Step 2 - Replacements
=====================
In order to eliminate bundling similar and/or derivative fonts, we can
substitute less useful fonts with others, similar to when Bitstream Vera was
replaced by DejaVu. Open Sans resembled Droid Sans and has limited language
support (Latin, Greek and Cyrillic) and doesnt have a serif equivalent that we
can bundle. So we should replace this with the Droid derivative Noto font
family, which has both sans and serif and unlimited language support, but i
would suggest limiting the languages to what is covered in Deja Vu to begin
with, which would take up 3.1 MB. (Tomaz and Adolfo both recommended this in
bug 91150)

Step 3 - Additions
==================
With the removals and replacements, the fonts now take up ~16 MB and we can
begin not only adding english fonts but open source fonts for languages we
previously didnt support through our bundled fonts.

I will include addition suggestions in follow up comments on the bug report
once my research has completed.
