Hi Stephen:

Thanks for your further comments.  I have no knowledge of CAD other
than what I can quickly read in wikipedia.  Nevertheless, it sounds to
me like you have completely answered my question on interoperability.

I am not as satisfied with your response to my concerns about your new
device's ability to deal with unicode text (e.g., examples 23 and 24
rather than 6 or 7) and dealing with fills and gradients (example 25).
(Follow links at http://plplot.sourceforge.net/examples.php to see
what is possible with those examples for our modern devices.) I
emphasize my concerns are not serious feature requests because I don't
have CAD needs myself, but they are issues I think you should at least
be aware of if you or some other CAD user develops a future need for
fills, gradients, or unicode text processing.

I think I do understand your expressed feeling that your new device is
good enough for your current needs so you want to be done with
developing it now.  I have lots of software of my own that I
have developed over the years which is in that category.  :-)

That said, it is a completely different ball game if you want your
software to be used by others.  For that category of software,
development never stops (for example, PLplot is approaching 25 years
in age, and we are still developing it!) So maintenance and
willingness to respond to feature requests is always an on-going
concern for public software. To illustrate that point, we have a lot
of PLplot devices where we have gone through (or are going through)
the painful decision to retire them because there is nobody external
or internal to the project who is interested in maintaining them any
further.  So if you decide you do want to donate your device to
PLplot, my opinion is we would probably need reassurance from you
before accepting it that you are interested in the long haul in
maintaining it and responding to real feature requests that will be
inevitable if the CAD community starts using it. Of course, that is
just my opinion and others here may have different ideas.
