    What I would like to be able to do is to supply a depth 1 tiling
    pixmap and have the server replicate the tile on the destination
    no matter what depth the destination is.

You still haven't made precise what you mean in this case, in terms
of exactly how the destination is affected.  However, I'll assume
from your later reference to copy-plane that what you mean is "use
the foreground and background pixels and the bitmap to construct a
real tile (essentially doing an opaque stipple), and then use that
tile".  The problem then is that, for a destination of depth 1, there
is an ambiguity: is the "tile" actually a tile, or should it be
reconstituted using the foreground and background pixels?  Rather
than trying to figure out how to resolve this ambiguity, the burden
is placed back on you to construct the tile yourself (e.g. by doing
a :bitmap put-image into the tile, or by doing a copy-plane into it).
It only takes a few lines of code to do this.
