[Plplot-devel] cgm driver reasonably stable now

[Alan W. I. <ir...@be...>]

With the fix to cgm.c that I just committed, all cgm files are generated
smoothly in all modes I tested.

I only found 3 minor rendering problems using visual inspection of the 211
(!) pages of test results in non-familied mode.  I also did some spot checks
in familied mode.

In non-familied mode, page 4 of x16c has red and rather fat contour lines
rather than the expected thin, yellow contours.  In familied mode the colour
is fine, but the contours are still fat in error.

Also in non-familied mode, p. 6 of the pythondemos and tcldemos has a red
grid rather than the expected yellow grid.  This error does not occur
for familied mode.

Andrew, you should be able to see the fat contours for page 4 of x16c in
familied mode, but you will need to install a cgm viewer (ralcgm might
be suitable for your system) that displays multiple pages to look
at the non-familied errors.

I don't know what exactly is clobbering the colour and width on such
relatively rare occasions.  But I think you are the one that should sort
this out since you are most familiar with how colour is handled in cgm.c. It
would be nice if you could get this fixed up before the release, but if you
don't have time now, that is fine as well since these cgm rendering problems
occur so rarely.
