Backports PHP internal functions to libgd.
Sorry if the question has been already asked.
I'm wondering why libgd doesn't backports internal PHP's GD functions like imageantialias, imagefilter and imagerotate?
There is issues like this (https://bugs.launchpad.net/ubuntu/+source/php5/+bug/74647) which is very old.
Is there any problems to backport PHP internal functions?
