fltk/fluid/align_widget.cxx
Michael R Sweet 81bd60b47d More UI cleanup. 
fluid/*.fl:
    - Go through all of the UIs and make sure they conform to the
      UI guidelines.

fluid/fluid.cxx:
    - Change fl_ask() and fl_choice() to use the "Save"/"Don't
      Save" and similar button labels instead of "Yes" and "No",
      per UI guidelines.

fluid/factory.cxx:
fluid/Fl_Type.h:
    - Make sure that widget and type names are capitalized.
