We had looked all of these and each had fallen short in some major
way (though I thought piddle had much promise and perhaps could be 
built on; however it was intended as a back end only.)

This we had not seen. A superficial look indicates that it is worth
investigating further as a basis for a plotting package. I didn't
see any major problem with it that contradicted our requirements,
but obviously we will have to look at it in more depth to see if that
is the case. It doesn't have to be perfect of course. And it is much
more expensive tto start from scratch (though we weren't doing that
entirely since a number of components from the chaco effort would 
have been reused). But this is worth seriously considering.
