    Simpler implementation of Fl_Cocoa_Window_Driver::resize()

1. Modified the resize.cpp program, adding this one line above Fl::run() to detect the error:

    if ( window->w() == 25 ) exit(1); else exit(0); // exit(1)=FAIL, exit(0)=OK

2. Created a script called 'bisector' in the fltk directory with the contents:

      #!/bin/sh
      make clean && ( cd src ; make -j 4 ) && ( cd test ; ../fltk-config --compile resize.cpp )
      test/resize
      exit $?

3. Ran git bisect with the start/end commits from the fltk main directory using:
      git bisect good 6838814f9e6433fc93ff73f4415fe30bbd7ed326
      git bisect bad 23484c30a9126dcda3f589cd63e3fe2ec8b41c98
      git bisect run ./bisector
