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.
