Does this work? GR_DEBUG was always 0 or 1, but SK_DEBUG is just defined.

just learned something new today :)

#if vs #ifdef.

If I understood this preprocessors of C right, #if is the macro equivalent of if
clause, and #ifdef is actually just testing if the macro was defined or not, it
doesn't care if the macro has a value or not.

 #endif // SK_DEBUG
     { SkBitmap::kARGB_8888_Config,  "NULLGPU",      0, kGPU_Backend,          GrContextFactory::kNull_GLContextType,   true     },
 #endif // SK_SUPPORT_GPU
