Try the PIXELS keyword, e.g.,

shade_surf, z, x, y, pixels=1000

The PIXELS keyword sets the maximum size of the image rendered by
SHADE_SURF. This keyword is honored on devices with scaleable pixels,
(notably the PS and CGM devices), and is ignored otherwise. See p. 279
of my book for more details.

Cheers,
Liam.
