    13 // Description:

    14 // This file has been added to solve a dependency issue raised in INC102308. 

    15 // LookupTable.h and BlendingAlgorithms.h are two Internal technologies that were 

    16 // implicitly included in GDI.h. However, when building third-party releases of the OS

    17 // these files are removed from the graphics directory, making them unreachable by 

    18 //

    19 

    20 // #include in GDI.h which causes the dependency failure.

    21 // The solution here is to make the functions calling the inline functions in 

    22 // LookupTable.h and BlendingAlgorithms.h non-inline as they were. Rather we will 

    23 // export them within this file. Now the functions are safe to be called from other 

    24 // components and they are not dependent on the headers.  

    25 //
