Do you envision any problems stemming from setting the same WM_CLASS
("r_x11", "R_x11") for rgl windows as used by x11() windows?
I think
that most DEs are able to group windows by WM_CLASS in addition to
WM_HINTS.window_group (Xfce does that by default, GNOME turned out to
just need a hint in the .application file).

Since early 2013, rgl has set the WM_CLASS to ("rgl",
"R_x11").  So I
think with your suggested change to R.desktop the problem is solved, 
assuming the first component (res_name) doesn't matter as long as the 
second one (res_class) matches.
