gEDA: Postscript output upgrade status and questions

[Mike Jarabek <mjarabek-at-NOSPAMistop_dot_com>]

Hi All,

    I have been working quietly in the background on cleaning up the 
postscript output for gschem.  So far, with my local copy, on my test 
`schematic' the output Postscript file shrinks by about 50%.  I have all 
of the basic drawing primitives working, a prolog from a file is copied 
into the output, and am about 30% of the way through the final 
primitive, text. (Unicode support, overbar support on postscript fonts, 
and postscript multiline text support.)  I few questions have come up 
while re-coding the output that I am seeking clarifications for.

    1) What units is the line width expressed in?  Is it in mils, 
postscript native points, or in some other unit?

    2) I may have to look into this some more, but the dots in the 
`center' and `phantom' line styles look a little anemic, and this seems 
to be because the dot is drawn at half the line width. I am not sure if 
the effect is because of rounding at the printer or because of design. 
 Right not, I set it up so that the dots are rendered at the full line 
size for the printer.  Does anyone object?  (I did see code in there 
that messed with the dot size, when I replicated this code in the output 
postscript, the results looked anemic, plus, the old output also looked 
pretty thin on my monitor.)

    3) What units the the text size in?  Is it in units of 10mils, or 
points?

Thanks,
Mike
