[Rd] [Solved] Possible x11 window manager window aggregation under one icon?

[Duncan Murdoch]

With that change to the .desktop file, both the existing rgl and the rgl 
with a group_leader set behave the same:  all x11() and rgl windows are 
collected together into the same R icon.

If I don't make that change, then setting the group_leader causes all 
rgl windows from one process to group together (with a bad icon).

I think I'll leave the group_leader in place.  I'll think about setting 
an icon, but I don't see it as urgent.
