Last time I saw a message similar to this I posed a few questions
to the comp.windows.news group about operations I feel are essential
for engineering graphics that don't seem to be possible in NeWS.
I have received no responses or feedback.  Once again,  I would

1.  Raster operations other than copy or xor.
2.  Color map modifications to directly specify a color.
3.  Plane management (masks) for independent control
    of multiple planes.
4.  Stipple fill of rectangular and non-rectangular regions
    on *color* devices (this is NOT the same as tiling with
    an or operation).  The stipple must be interlocked (relative
    to a known point regardless of the location of the
    stippled object).

I have written an editor for Computer-Aided Design of Integrated
Circuits under X10 which uses *ALL* of these features.  Furthermore,
most CAD of IC graphics editors I know of require most if not
all of these features.  As far as I can tell,  these editors
cannot run on top of NeWS.
