[Fontconfig] Making Aliases Conditional

[Akira TAGOH]

Hi,

alias/prefer thing like:
<alias>
    <family>serif</family>
    <prefer>
        <family>Font Name</family>
    </prefer>
</alias>

can be replaced with:

<test name="family">
    <string>serif</string>
</test>
<edit name="family" mode="prepend">
    <string>Font Name</string>
</edit>

not tried but I guess there should be some docs there though, how it's
translated to test/edit things for aliases are documented in fonts.dtd
at least.

HTH,
