[STR New]

Various printers/drivers provide various levels of "draft" mode, intended
to save Ink/Toner.  Some work, some not so much, and some don't even
bother with such an option.

I discovered something called "Ecofont", a scaleable font with largish
holes cut out of it amounting to about 20% of the coverage area.  I
noticed that on all of my printers (2 laser, 1 ink) the holes weren't even
visible until scaled quite large.

The concept is to add a print option at the CUPS level, w/o knowledge of
the drivers, such that the CUPS raster API will automatically cut a simple
1 pixel checkerboard pattern of white out of the raster planes delivered to
rastertoXXX drivers.  That's a draft mode for everybody, with a 50%
consumable savings.
