This is written in Objective C++, which is the union of C++ and Objective C;
Their intersection is C or almost. They add quite different sets of features.
I need Objective C here because the Cocoa API is for Objective C and Java only,
and the Objective C one was the easiest to integrate in GridFlow.
The next best possibility may be using RubyCocoa, a port of the Cocoa API to Ruby;
However I haven't checked whether Quartz is wrapped, and how easy it is to
process images.
