I found the ppe source complex and unhelpful, so I'll recommend
against looking at it if you're already confused.

Steve and others have assured me that it's easy to pick the SSG
entities under a screen location with existing SSG code.  Could
someone please explain precisely how?  Let's assume that I have

  ssgRoot * root;

and

  ssgContext * context;

Using PUI, I receive a mouse click at x=30, y=50.  Now, exactly what
C++ code would I use to get the list of ssgEntity objects under that
screen location?


Thanks, and all the best,


David
