[Therion] Height numbers in square boxes

[Bruce Mutton]

Well, this is beyond my expertise, but I have collected together some clues from the code, in the attached file.
Maybe someone else can make something of it.
It seems like the distributed metapost code has boxed label capability built into it, but the overall implementation does not provide a way for it to be used (maybe).
The C code allows for all the 'modes' to be used, except mode = 6 for boxed labels and mode = 8 for filled labels.  So looks like there needs to be changes at that level.

It might be that this capability is already built into Therion.

Look in the source files.
/mpost/thText.mp line 84: 
vardef p_label@#(expr txt,pos,rot,mode) = ...
  elseif mode=2: process_uplabel;       
  elseif mode=3: process_downlabel;
  elseif mode=4: process_updownlabel;
  elseif mode=5: process_circledlabel;
  elseif mode=6: process_boxedlabel;
  elseif mode=7: process_label(pos,rot);  % station name
  elseif mode=8: process_filledlabel(pos, rot);
  else: process_label(pos,rot); fi;

/mpost/therion.mp line 440: 
def process_boxedlabel =
    q:=bbox lab;
    draw lab;
    draw q;
    write_bbox(q);
enddef;

/mpost/therion.mp line 484:
def write_bbox (expr q) =

I think we just need to figure  out how to invoke the various modes, and we can make use of the predefined label ornaments.
Unfortunately I don't have time to play with any of this just now, I'm sure one of you will figure it out.
