// 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.  

//
