Controlling the XFT fonts that exmh uses for message display?

 I'm considering switching my exmh to use XFT fonts (via switching to
tk8.5), in part to match the rest of my X environment and in part to get
better Unicode font support (I'm very used to my old X bitmap fonts, but
they are behind the times).

 The choice of what fonts to use when for MIME messages is normally
controlled by the *mime_<charset>_<type>_families: resources in
exmh-defaults, eg '*mime_iso-8859-1_plain_families' (and then the
starting size is set with *mimeFontSize). So normally I might just
set some face names in those resources.

 However, looking at the code in lib/mime.tcl's Mime_GetFont() (which
actually does the lookup) suggests that this isn't going to work; its
implementation seems very strongly tied to XLFD font names. Run on a
tk8.5 that supports XFT fonts and not XLFD fonts, I expect it to fail
entirely and give me only (at best) whatever *Msg*font is set to (or the
XFT 'fixed' by default). This seems less than ideal, especially for MIME
types that want a proportional font or different font sizes.

 Has anyone dealt with this issue and gotten exmh to use XFT fonts
well for message display, or am I barking up the wrong tree here?

(Or is this something that I should really ask on exmh-devel instead?)

PS: In theory one could revise Mime_GetFont() et al to do an XFT-based
font specification and font lookup if TK is XFT-capable, but this sort
of change is probably beyond my TCL/TK/XFT coding capabilities right
now. If I got something working it would probably not look very well.
