Branch :
The OpenCL headers ANGLE uses are the original headers from Khronos, but they are modified to allow
the macro CL_API_ENTRY to be overridden externally.
The modifications have been submitted to Khronos, and this document should be updated after they are merged.
Copy all headers from OpenCL-Headers/CL/ over to this folder.
Edit the headers:
Change all occurences of typedef CL_API_ENTRY to typedef.
In cl_platform.h change both #define CL_API_ENTRY to
#if !defined(CL_API_ENTRY)
#define CL_API_ENTRY
#endif
