+// Description:
+// This file has been added to solve a dependency issue raised in INC102308. 
+// LookupTable.h and BlendingAlgorithms.h are two Internal technologies that were 
+// implicitly included in GDI.h. However, when building third-party releases of the OS
+// these files are removed from the graphics directory, making them unreachable by 
+//
+
+// #include in GDI.h which causes the dependency failure.
+// The solution here is to make the functions calling the inline functions in 
+// LookupTable.h and BlendingAlgorithms.h non-inline as they were. Rather we will 
+// export them within this file. Now the functions are safe to be called from other 
+// components and they are not dependent on the headers.  
+//
