          them to a set of routines belonging to the type of input we're
          using.  Set them to .pbm input format routines as a default.
          (font_name_extension): Added this static variable so could set
          it when get read the input format on the command line.  Set to
          `.pbm' by default.

          vert-resolution to the option variable long_options.
          If the argument is horz-resolution or vert-resolution, then set
          the appropriate field in the header.
          If the argument if img-input-format or pbm-input-format, the set
          the input function pointers in main to the appropriate set of
          functions that belong to the input format.  If the argument is
          the former, then set needs_resolution to false; if it's the latter,
          set it to true. 
          If the user wants .pbm input format, then check that the header's 
          resolutions are set; if not, issue an error message and exit. 
          
        * main.h (open_input_file, close_input_file, get_header, get_scanline):
          Added these function pointer declarations so extract.c and strips.c

        boxes that are on the edge.

        output, omitting the ones out of range.
        
        * main.c (clean_bitmap): print gray values for the bounding boxes
        if requested.
        (read_command_line): new option, `print_clean_info'.

        * extract.c (some_black_to_all_white_row): don't output a newline
        after reading the scanlines.

        (some_black_to_all_white_row): call it, at the end, with a new
        variable that is the logical or of all the rows we read.
        (some_black_to_all_white_column, found_color_in_column): these
        routines aren't needed any more.
        * main.c (do_image_line): use the transition vector to set
        `char_bitmap'.

        * main.c (scan_integer_list): increment length after checking the
        exit condition.

        * main.c (do_image_line): new routine, consisting of a lot of the
        main loop.

        (read_command_line): new option `baselines' to set the baselines.

        * main.c (bitmap_to_gf_char): take another argument, the character
        code, to consolidate where the GF char is set.

        * main.c (nchars_per_line): new static to say how many characters
        we can report on per line; different for `print_guidelines' being
        set and not set.

        * main.c (print_guidelines): new global.
        (read_command_line): new option to set it.
        (bitmap_to_gf_char): print the row numbers if it's set.

        * bb-outline.c (find_outline_bbs): take two additional arguments:
        column numbers between which we don't look.
        * bb-outline.h (find_outline_bbs): change the declaration.
        * main.c (main), (clean_bitmap): change the calls.

        * bb-outline.c (append_bounding_box_list): reallocate based on the
        element size, not the list size.

        * bb-outline.c (set_bounding_box_list_offset): replace by
        `offset_bounding_box_list'.
        (append_bb): don't offset the bounding boxes as they come in.
        * bb-outline.h (set_bounding_box_list_offset): likewise.
        * main.c (main): change call.

        * main.c (output_chars): set char_code to *next_code at the bottom
        of the loop, and increment next_code.

        * bb-outline.c (set_bounding_box_list_offset): new routine.
        (append_bb): move the bounding box to the right by the offset.
        * bb-outline.h (set_bounding_box_list_offset): declare it.

        * main.c (get_char_code): rename to get_encoding, and read the
        whole file.

        * bb-outline.h (init_bounding_box_list, append_bounding_box_list):
        declare new routines.
        bb-outline.c (same): define them.

        * main.c (main): don't split each line at white columns.

        * extract.c (clean_bitmap): set verbose to false before calling
        find_outline_bbs.

        * main.c (get_char_code): make sure we actually find a character
        code.

        * main.c (output_chars): don't extract or clean anything if the
        character isn't within range.

        * extract.c (REPORT_SCANLINE): report every 100 scanlines.

        * main.c (output_chars): only give the status report if we
        actually output the character.

        * bb-outline.c (append_bb): changed MAX_ROW, instead of MAX_COL.

        * main.c (clean_bitmap): new routine.
        (output_gf_chars): call it.
        * bb-outline.c (find_outline_bbs): take an additional parameter to
        determine whether to look for inside outlines or not.

        * extract.c (REPORT_SCANLINE): report every 50 scanlines, instead
        of every 10.
        
        * bb-outline.c (find_outline_bbs): look for outlines in
        column-major order, instead of row-major.
