I think that the consensus is that the 'pbm/pgm/ppm/pkm' class of devices are
adequate to cover the mono/gray/rgb_contone/rgb_cmyk devices.

As discussed elsewhere, adding the 'tiffsep' or some other device that supports
encoded colors and spot color overprinting would be useful.

The other class of devices are "high level" devices. These are unique in that
they use the 'gdevvec' mode. Included are pdfwrite (already part of regression
testing), ps2write (being discussed), pswrite (mostly deprecated), pxl***
(the topic of this thread) and a few other fledgling devices such as svg and
cairo.

Any devices which support spot colors, or have their own implementation of
high level functions or colors including 'fill_path', 'stroke_path' and
'fill_rectangle_hl_color' as well as custom 'devn' functions need to be
considered.
