In samples: - Fixed syntax error in DataExchangeDemo.tcl - MSAA is enabled in some tests to provide better presentation - Option to build isolines on triangulation is used in some samples to avoid artifacts in selection highlight - Colors are corrected in cpu.tcl In documentation: - Reference to automake tools is removed - Standard_OVERRIDE is expanded to "override"
