Hi Jim
There is still a bug in the buffer with respect to the correct state
parameters. I think we discussed this in the past regarding plplot
initialisation, but this particular bug occurs at page change.

Basically at the beginning of a render, plplot inherits it's state
from the previous render. Mostly when we simply move from one page to
the next this behaviour gives expected results. However if we rerender
a page twice, then the second render inherits the state from the first
render which is wrong.

A good example is x19.4. At the end of this page the colour table is
changed (including the background colour) in preparation for page 5.
If you resize page 4 under the X driver you will see that the
background and lines change colour because this new colour table is
being incorrectly used.

I have seen a similar thing happen with the line width and presumably
other state variables behave similarly too.

Basically I wanted to check if this is something that is on your
radar? I am happy to fix the problem, but I don't want to create a
clash with your current work.

Phil
