Mathematica graphics and J/Link

Hi,

I am interested to know if there are any packages out there which solve 
the problem of doing interactive Mathematica graphics using J/Link. 
Obviously you can display your graphics in a mathCanvas window, but any 
mouse messages relate to pixel coordinates and not to the coordinate 
system of the original Mathematica plot. Furthermore, the relationship 
between the two coordinate systems will change if the window is resized 
by the user or (sometimes) if the graphics are changed.

The sort of program I have in mind might (say) populate a graph with 
data supplied using the mouse.

The reason that I ask is that I have devised what I believe is a pretty 
effective solution to this problem (by temporarily modifying the plot 
with calibration marks). If there is nothing adequate out there I will 
do the work to polish it up for MathSource.

Are there any plans to supply reliable pixels to Mathematica coordinate 
conversions in J/Link (or is there something in there already that I 
have missed).

Regards,

David Bailey
