// 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
|
|
sl@0
|
16 |
// implicitly included in GDI.h. However, when building third-party releases of the OS
|
|
sl@0
|
17 |
// these files are removed from the graphics directory, making them unreachable by

|
sl@0
|

// #include in GDI.h which causes the dependency failure.
|
|
sl@0
|
21 |
// The solution here is to make the functions calling the inline functions in
|
|
sl@0
|
22 |
// LookupTable.h and BlendingAlgorithms.h non-inline as they were. Rather we will
|
|
sl@0
|
23 |
// export them within this file. Now the functions are safe to be called from other
|
|
sl@0
|
24 |
// components and they are not dependent on the headers.
