Thanks for the patches. I have applied them, with some small changes:
- I put them in point.h and affinetrans.h to keep the code more organised.
- AffineTrans::apply() didn't seem to be implemented so I did so, which caused
me to also reimplement the internal data of Point as a C ArtPoint. Therefore I
added get/set accessors for the x and y values.
- I added copy constructors (and therefore operator=).

Please use the sourceforge Patch Manager in future and make your patches
against the cvs module by typing something like this:
cvs diff -u3 > somefix.patch

I removed the typedef and changed the example.

Please do. You should be able to get the CVS version anonymously after approx
24 hours. If not, then I'll send you a tarball.

- See my comments above. It's in gnome-libs/libart_lgpl/art_point.h

Just include types.h. We already use string.
