+-- RPR API CHANGE:
+ * Minor API backward compatibility break:
+   rprsExport, rprsImport, rprImportFromGLTF, rprExportToGLTF have a new argument: rprsCtx.
+   This "import/export" Context will be used to store additional data for the Export or read additional data after an Import.
+   This argument can be set to NULL in order to have the same behavior than before 2.02.6.
+
+ * new material for Northstar: RPR_MATERIAL_NODE_BLACKBODY.
+   inputs of : RPR_MATERIAL_INPUT_TEMPERATURE , RPR_MATERIAL_INPUT_KELVIN , RPR_MATERIAL_INPUT_EMISSION.
