[OpenJDK 2D-Dev] [Accessibility]Add fontconfig.properties files for SLES10/11, RHEL5, Ubuntu 8.04 etc

[Phil Race]

Hi,

Let me try to explain it a bit more.
Oracle has chosen to "certify" a small number of Linux distros because 
we can't test them all.

That is 100% unrelated to which distros have a fontconfig.properties.

We can certify just fine on ones that DO NOT have such a file.

ie existence of fontconfig.properties != certifiable.

The existence of such a file for ANY distro in JDK 7 can be considered 
"legacy" or
"wholly unnecessary".
If you create one you have to go to the trouble of finding good fonts 
you KNOW
will be there and you have to figure out where they are etc.

OpenJDK can't even rely on the Lucida fonts (I hope your patches weren't 
relying
on them else the assertion this would help openjdk would be very far 
from the
truth) that we traditionally used for support of West European.

The maintenance issue is that when Ubuntu.NEXT comes out, you need to
provide a new file. Now its darn near impossible, unless you are the distro,
to sync up a JDK release with an Ubuntu release.

So whilst I see no problem with Ubuntu providing a custom file with their
bundled OpenJDK build, they don't need to if they don't want to. But
every one else should keep well away

We do not have the resources to keep up.
So the supported, standard, going forward solution is to NEVER use these 
files.

We came *this close* to deleting the lot of them in JDK 7, even the ones you
see now. A few were kept around for reasons that were not essential.

So that, in a long nutshell, is why I don't want to see them re-appear, 
especially
for OpenJDK and especially for platforms we aren't going to be able to test.
