[Therion] Metapost modifications

[Footleg]

Take a look at Bruce's customised symbol sets on the wiki. I based mine on
those. I have not tried adding a completely new symbol to therion yet, but
here is how I override the pebbles area fill with one which looks more like
I prefer. Include this layout in your pdf export command to see pebbles
rendered with this custom style:

layout CustomisedSymbols
  code metapost

beginpattern(pattern_pebbles);
pickup PenC;
path qq;
for i=0.0u step 0.6u until 5.1u:
for j=0.0u step 0.6u until 5.1u:
  qq := (superellipse((.05u,0),(0,.05u),(-.05u,0),(0,.-.05u),.75))
 randomized (u/45)
 scaled (uniformdeviate(1.2)+.55)
 rotated uniformdeviate(360)
 shifted ((i,j) randomized 0.55u);
   draw qq;
endfor;
endfor;
patternstep(5.1u,5.1u);
endpattern;

def a_pebbles (expr p) =
T:=identity;
thfill p withpattern pattern_pebbles;
enddef;

  endcode
endlayout CustomisedSymbols
