    Fix stmaryrd operators with limits (bug 9458)
    
    LyX did not display the limits of the big math operators defined by
    stmaryrd.sty correctly. The reason for this was a missing check in
    InsetMathSymbol::metrics(), where it is hardcoded which symbols use display
    style limits and which symbols use inline limits. In an ideal world this
    information would be contained explicitly in lib/symbols.
