NOTICE: This module requires libgd 2.0.5 or higher.
        it will NOT work with earlier versions. If you are getting
        compile or link errors, then please get and install a new
        version of libgd from www.boutell.com.

Writing Makefile for GD::Image::CopyIFS

You can now run

   make
   make test
   make install

The tests will create, in the t/ subdirectory, zoomed-in 
areas and a resized image based on the original lena.jpeg
image. These images are all named "*_ifs.jpeg"; one can
compare these with the analagous "*_resized.jpeg" and
"*_resampled.jpeg" images made with, respectively, the
"copyResized" and "copyResampled" methods of GD.
