Routine Description:

    Creates a Form entry, and insert it into the right place in
    pIniSpooler.

Arguments:

    pFormName - Name of Form.

    Size - Size of form.

    pImageableArea - Area of form that the printer can print to.

    Type - Type of form (usually indicates if BUILTIN form).

    cFormOrder - Where the form should be inserted for user-defined forms,
        form order increases from beginning to end.

        If this value is -1, generate a new cFormOrder for this form.
        (Put it at the end.)

Return Value:

    pIniForm - Created form, NULL = error.

Notes:

    This routine ensures that forms are put in proper order so that
    EnumForms always returns them in the same order.  We do this by
    scanning the list and inserting the new form such that all forms
    with cFormOrder =< the current on are to the left of it.

    This routine updates pIniSpooler->pIniForm (inserts or appends) and
    updates pIniSpooler->cFormOrderMax if necessary.

    i.e., 0 0 0 2 3 4 6
               ^
           New 0 inserted here.
