BUG: layout mode text extraction ZeroDivisionError (#2417)

For fonts without an explicitly defined width for the " " character, it's still possible to generate a ZeroDivisionError when compiling TextStateParams objects in _fixed_width_page.recurs_to_target_op() if the font size or the Tz parameter has been set to 0. 

Discovered during processing of a "pre-OCR'd" image PDF having `{"/BaseFont": "/GlyphLessFont"}`.
