          * src/type42/t42drivr.c, src/type42/t42drivr.h, src/type42/t42parse.c,
            src/type42/t42parse.h, src/type42/t42objs.h, src/type42/t42objs.c,
            src/type42/type42.c:
  
              updated the Type42 driver by splitting it into several files since
              it makes the code easier to read and maintain. Also fixed the bug
              that prevented the correct display of fonts with "ftview"
