public delegate void FormatUnpack (FormatInfo info, PackFlags flags, void* dest, void* data, int stride, int x, int y, int width)
Unpacks width pixels from the given planes and strides containing data of format info.
The pixels will be unpacked into dest with each component interleaved as per info's unpack_format, which will
usually be one of ARGB,
AYUV, ARGB64 or
AYUV64 depending on the format to unpack. dest should at least
be big enough to hold width * bytes_per_pixel bytes where bytes_per_pixel relates to the unpack format and will usually be
either 4 or 8 depending on the unpack format. bytes_per_pixel will be the same as the pixel stride for plane 0 for the above formats.
For subsampled formats, the components will be duplicated in the destination array. Reconstruction of the missing components can be performed in a separate step after unpacking.
