My distro does not care about rendering color emojis. Building my image 
now pulls in libpng unless I remove the packageconfig in a distro conf.

The pixmap packageconfig has defaulted to being off since it was added 
in 2013 in commmit 7cbf6060ac14b0f4d2f038f821ca980be0d46cb0. Wouldn't it 
make sense to keep it off by default and let whoever needs it enable it ?
