Post title says it all, I'm trying to get coordinates for the cursor at the end of a drag (or directions to documentation or listings that will let me figure it out).

I'm trying to port an old EJS app of Paco's that I did some small mods to years ago called particles and walls.  In that Java app, there was access to Pos X and Pos Y, but that doesn't exist for the drawing panel.  I'm assuming it will be just a method call, but I can't figure out what that might be.
