#22531: libdevil scaling filters do not work when reducing images

Hi,
The following code should generate a high-quality thumbnail (I am using
the lanczos3 filter): http://gist.github.com/234637
However, the resulting thumbnail is of very poor quality, it is almost
indistinguishable from the nearest neighbor algorithm.
This is particualrly strange behavior because in Debian Linux using the
libdevil1c2 / libdevil-dev package the thumbnail quality is very high, as
expected.
What is the difference between the Debian package and the macports
libdevil package such that the filters work in Debian but not on macports?
It is very important that the high-quality filters work properly as
thumbnailing is a very common application of DevIL.
