I'm not sure if changing the meaning of the align() member is such a good idea.

    Right, realized that as I was implementing.

    I was thinking the extra bits in align() could be used, but yeah, perhaps that's a bad idea,
    as the reserved FL_ALIGN_XXX bits might be used for something else in the future, and there
    isn't a FL_FREE_ALIGN (like we have for label types) to identify where reserved bits start.

    So I can think of a few ways to do it:

    1. Add a new Fl_Align _input_align; member value, and add an accessor pair to manage it:

        void input_align(FL_ALIGN_LEFT|RIGHT);     Fl_Align input_align() const;

    2. Use the accessor names in #1, but use the internal Fl_Input widget's align() value to hold
        the LEFT/RIGHT state (avoids creating a new member value), since Fl_Input's label() is never shown.

    Perhaps there's better ideas -- defining API's was never a personal strong point.

However, this is a specialized widget and we could add another flag member if necessary. It's now a good time to change the ABI before FLTK 1.4.0 will be released.

Right, that's what I was thinking.
