BGT portrait naming conventions, for BG1 NPCs Options

[cmorgan]

Sorry for the crosspost, but I am definitely under the gun for a deadline by mid Sunday...

CODE

/* Imoen */
BEGIN @380
GROUP @379
REQUIRE_FILE ~override/X#BG1NPCCore.G3~ @4
ACTION_IF FILE_EXISTS_IN_GAME ~FW0100.are~ THEN BEGIN
COPY_EXISTING ~NImoenm.bmp~ ~override/_moenl.bmp~
COPY_EXISTING ~NImoens.bmp~ ~override/_moens.bmp~
END
ELSE ACTION_IF FILE_EXISTS ~data/AREA000A.bif~ THEN BEGIN
COPY_EXISTING ~NImoenm.bmp~ ~override/moenl.bmp~
COPY_EXISTING ~NImoens.bmp~ ~override/moens.bmp~
END

I just did a bunch of research, and thought that BGT used portrait conventions like imoenL.bmp imoenM.bmp imoenS.bmp.

Then I ran into the second part of that above code. It could be an error/artifact of mass conversion to BGT, but I am a paranoid dude who wants to make sure both Tutu and BGT folks get content ---

for once and for all, can someone provide a list of the portrait formats used in BGT to give BG1 NPCs their portraits correctly?

I would be eternally grateful....
