[cairo] Extents under rotation

[Donn]

Uli,
Your c code is really interesting. How do you compile it? It's a newb 
question, but I have that disease :)

I've tried:
gcc $(pkg-config --cflags --libs cairo) uli_test.c -o test

But it's missing something - due to many undefined references. E.g:
/tmp/ccDh8JkD.o: In function `get_surface':
uli_test.c:(.text+0x1c): undefined reference to `cairo_image_surface_create'
uli_test.c:(.text+0x2c): undefined reference to `cairo_create'
uli_test.c:(.text+0x3c): undefined reference to `cairo_surface_destroy'
