On Windows, all bitmap devices (bmp(), jpeg(), png(), tiff()) will give
better-looking (anti-aliased) pictures with type =3D "cairo" instead of
type =3D "windows".

On Linux, type =3D "cairo" also produces better-looking bitmaps than type
=3D "Xlib". On macOS, type =3D "cairo" and type =3D "quartz" should produce
bitmaps of similar (good) quality.
