// 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.  
//

#include <graphics/lookuptable.h>
#include <graphics/blendingalgorithms.h>
#include <gdi.h>
