Bugzilla Bug 93100

After emerging mathematica-fonts-4.2, I get this message while viewing many
pages:
To properly display the MathML on this page you need to install the following
fonts:
Math1, Math2, Math4.

Here's one from the W3C test suite
http://www.w3.org/Math/testsuite/testsuite/TortureTests/Complexity/complex2.xml

It seems that the major difference is in names. For example, Mathematica1.ttf
(4.2) probably corresponds to math1___.ttf (4.1)

If you read the comments to mozilla bug 128153, you'll see that the fonts used
are configurable via the pref font.mathfont-family . We could add a note to the
ebuild to change the pref or add aliases.
Pref solution (includes change to use Standard Symbols L per mozilla bug
236880):

pref(font.mathfont-family, "CMSY10, CMEX10, Mathematica1, Mathematica2,
Mathematica4, MT Extra, Standard Symbols L")

Alias solution (example):
  <match target="pattern">
    <test name="family">
      <string>symbol</string>
    </test>
    <edit name="family" mode="append" binding="strong">
      <string>Standard Symbols L</string>
    </edit>
  </match>

Obviously, Mozilla should be equally happy with either. I've filed a bug on
their end about it. Until then, it's up to the user to handle it.

Created an attachment (id=59239) [edit]
Patch to mathematica-fonts-4.2.ebuild

Tells the user how to make Mozilla & Co. happy with the 4.2 package.

Yes, pages render just fine with them.

Thanks. Applied the patch in CVS.
