[Therion] Changing symbols for area debris

[Gilbert Fernandes (mailinglist)]

Hello,

I try to change the symbols for my survey (small survey), and I follow 
the wiki to increas symbol numbers for area blocks, pebbles and debris.

It work find for blocks and pebbles area, but the changes for debris 
seams to not been taken in account.
I past my code for a_debris in the a_blocks definition, the symbols are 
well drawn (on blocks areas). So the code is good I thing.
Here the code.

     def a_debris (expr p) =
       T:=identity;
       % thclean p;
       pickup PenB;
       path q; q = bbox p;
       picture tmp_pic;
       tmp_pic := image(
       for i = xpart llcorner q step 0.3u until xpart urcorner q:
         for j = ypart llcorner q step 0.3u until ypart urcorner q:
           draw ((-.15u,0)--(.15u,0))
           rotated uniformdeviate(360)
           shifted ((i,j) randomized 0.3u) withpen PenA;
         endfor;
       endfor;
       );
       clip tmp_pic to p;
       draw tmp_pic;
     enddef;

Do you have the same problem ? may  be I have to add othe command lines ?
I use the windows release 5.2.7.
Thanks,

Gilbert
