I have long wanted a MACDraw like package for my Amiga, without
having to buy a CAD package. And this has been where this thread
has been going. Let's not forget about color.

MacDraw is easier to implement since it is in black and white, on a
color machine and with color printers I think a true structured graphics
standard would do to colors what vector drawing packages do for various
display devices. Let me elaborate with an example.

Suppose I was working with a color version of MacDraw and I had
access to a shadow like device as DPaint II has. In the underlying
database for this picture I would expect the shadow to be stored not
as "color these bits thusly" since that is in the raster rendering
paradigm, but I would rather expect the picture to be stored as
"cut the intensity of objects and portions of objects in this region
by half" or something. This could then be rendered in a variety of
means, which ever is best suited to the displaying device (dithering
for printers, HAM or HBRITE for Amigas, 256 colors for MacIIs, etc.).
