Subject: 0022082: EDF 1891 SMESH: Performance issues in SMESH filters

0022082: EDF 1891 SMESH: Performance issues in SMESH filters

In MapCells(SALOME_Actor*,const TColStd_IndexedMapOfInteger& theMap),
move the following code out of the loop on theMap

   UnShrink();
   if(theMapActor->IsShrunk()){
     SetShrinkFactor(theMapActor->GetShrinkFactor());
   }
   myMapIndex = theMap;
