    matrix-stack: Fix the _cogl_matrix_entry_equal function
    
    The _cogl_matrix_entry_equal function has a large switch statement to
    do the right kind of comparison for the entry. However most of the
    entries have a return statement that is only conditionally reached.
    There were no corresponding break statements to the case labels so
    presumably if the comparison succeeded for the correct entry type it
    would also flow through and try the comparison for the next type which
    would be extremely unlikely to pass.
