[comp.sources.d] More info on Vplot

Let me clear up a couple of questions:

Hanauma's IP number is 36.51.0.16, for those of you (like us)
without named.

I should also mention that the distribution is only a graphics Kernel;
it assumes you will provide your own utilities to sit on top of it.
We have a large number of such utilities here, but mostly they are
real hack jobs I wouldn't want to inflict on others.

Vplot's main advantage is that it can plot almost any graphical
primitive on almost any kind of graphical device. For example,
you can plot a color raster image on a Tek 4014. It would stretch
the raster to the device pixel grid, convert the color to grey
scale, dither the grey to black and white, and finally convert
the black and white raster to points and vectors...
We like to plot seismic data in raster form with vector axes and
labels on top of it on a wide variety of devices, and can't seem
to do it with anything else that's available.

A major project would be to keep Vplot's basic ideas, but make
it interactive and use postscript as a metafile...
