What do you mean by "tiled rendering"? I already split the rendering
into tiles, but it's still not possible to render paths that are
larger than 32767 pixels at the given zoom level, even if the target
surface has a size that is way below the limit.

It is possible to overcome this limitation outside Cairo for paths and
linear gradients, but it's not possible for radial gradients.
