Changeset 35644 for branches/eam_branches/ipp-20130509/psModules/src/objects/models/pmModel_QGAUSS.c

Message:

replace code which converts the PAR[SXX,SXY,SYY] values to shape and then axes with calls to pmModelParamsToAxes : the relationship depends on the model type. placing the code in a single function avoids inconsistent conversions
