 Please make 'plane' available to kernel function in program_opencl.
 For examle: now I'am working on fisheye to equirectangular conversion, and
 want to make unmapped pixels black.

 If I run in YUV pixel formats, then I can't do it, because kernel function
 have not information on which plane it is working. I have green or pink
 colors, but not black. 'format=rgba' can help, but more than twise
 decreasing performance.

 As a workaround I have to copy source pixel which a guaranted to be black,
 but it is also make 10% performance decreasing.
