Sawfish has Depth in the Placement tab (and Ignore stacking requests
in Other) of Matched Windows, so it can be done if I understood the
problem (and the program is not doing silly tricks). I guess you are
doing it via rc file instead of GUI.

Once running, that config is stored in variable match-window-profile
as ( [...]  (((WM_NAME . "foo")) (depth . -1) [...] ) [...] )
(sawfish-client real output, cropped to the right part) to make
windows named foo have depth -1. You want something like that, but 0
as value. ignore-stacking-requests is so the app is not brought to
front later.

Adapting the documentation example, with filler NAME and CLASS (use
xprop to figure right values):
(add-window-matcher '((WM_NAME . "FillerName")
                      (WM_CLASS . "^Filler/filler$"))
                    '((depth . 0)
                      (ignore-stacking-requests . t)))

Even if you dislike GUI, I would suggest creating one fake matcher
with everything enabled so you get examples of everything in the
custom file, as well as in sawfish-client. Remove it once you copy the
result for reference. Or check match-window.jl, it has
match-window-properties info.

Also you may use bindings to change the stacking (inside current
depth) and depth:
(bind-keys window-keymap "H-r" 'raise-window-and-transients)
(bind-keys window-keymap "H-d" 'lower-window-and-transients)
(bind-keys window-keymap "H-R" 'raise-window-depth)
(bind-keys window-keymap "H-D" 'lower-window-depth)
H- is Hyper key, d for down (just below the r key), upper case for big
change, FYI.

Cheers,
GSR
