[poppler] Fontconfig patch

[Stefan Kleine Stegemann]

Hi,

I finaly got PopplerKit working fine with fontconfig. This also improved
font handling in PopplerKit. The solution is to setup a custom FcConfig
object and set this as fontconfig's default configuration before poppler
accesses fontconfig. I now have one problem left with these two lines from
the patch:

FcInit();
FCcfg = FcInitLoadConfigAndFonts();

As far as I understand the fontconfig sources, FcInit creates a
new default configuration if it does not exist. The default
configuration can be set using the FcConfigSetCurrent function.
If a default configuration has already been set before FcInit,
FcInit simply returns without doing anything. FcInitAndLoadConfig
loads the system default configuration file and creates a FcConfig
with this file. FcInitAndLoadConfig is implicitly invoked by FcInit
if no default configuration has been set. So you acutally do the work
twice. It would be sufficient to call FcInit first and the use
FcConfigGetCurrent to get the default FcConfig. This way, I can set
up a custom FcConfig and set this as default (using FcConfigSetCurrent)
BEFORE PopplerKit initializes the poppler libary.

BTW: FcInitAndLoadConfig dumps core on OSX if it cannot load the
system wide fontconfig config file. So I have to avoid that it's
getting called.

Another option would be to provide a method to set the FcCfg from
outside.

Can you modify your patch accordingly?

greets & thanks
Stefan
