[Kayven Riese]

Is that why I am getting a seg fault?

     /**********************************

 82         cairo_set_font_size (cr, (1400.0*nuclear)/total);
 83         cairo_set_source_rgb (cr, 0.4, 0.2, 0.6);
 84         cairo_move_to (cr, BORDER+CELL_DIAM/2-3600*nuclear/total,
TOP_BORDER+1000*nuclear    /total);
 85         cairo_get_font_matrix(cr,fatrix);
 86         cairo_matrix_init_scale(fatrix,0.8,0);
 87         cairo_set_font_matrix(cr,fatrix);
 88         cairo_show_text (cr, "N");
 89         cairo_set_font_size (cr, (1040.0*nuclear)/total);
 90         cairo_show_text (cr, "ucLea");/**/
 91         cairo_set_font_size (cr, (1400.0*nuclear)/total);
 92         cairo_show_text (cr, "R");/**/
 93

Do the scale factors multiply or add?  I am supply sy = 0.. maybe I want sy
= 1
