Foundation Classes - Return value is overridden by OCCT #528
- Removed OSD_PerfMeter.h and integrated its functionality directly into OSD_PerfMeter.hxx. - Updated OSD_PerfMeter to manage stopwatches through a singleton StopwatchStorage class. - Enhanced meter initialization and management to support shared meters by name. - Implemented methods for starting, stopping, and printing elapsed time for performance meters. - Added OSD_PerfMeter_Test.cxx to implement unit tests for OSD_PerfMeter functionality. - Test bug23237 is delete as it refers to removed code.
