I assume you are talking about an image surface. All drawing to an image
surface respects the size of the image surface. Cairo does not draw
outside of the memory of the surface. The only way to get out of bounds
accesses should be to pass incorrect values to
cairo_image_surface_create_for_data().

Cheers,
