If you’re doing something pixel-based:

1. Do as in that link you gave
2. Save the result as PNG
3. Use cairo_image_surface_create_from_png() to get a cairo surface
4. Make a surface pattern from that
5. Set the pattern’s "extend" to CAIRO_EXTEND_REPEAT
6. Use the pattern as a source.


If you want vectors it’s gonna be more tricky: you’ll need to express 
the effect you want in terms of paths, colors, gradients, etc.
