* However, it is not enough because medialib lookup routine uses
* number of channels of medialib image. Note that in certain
* case number of channels may differs form the number of bands.
* Good example is raster that is used in TYPE_INT_RGB buffered
* image: it has 3 bands, but their medialib representation has
* 4 channels.
*
* In order to avoid the lookup routine failure, we need:
*
* 1. verify that src and dst have same number of channels.
* 2. provide lookup array for every channel. If we have "extra"
* channel (like the raster described above) then we need to
* provide identical lookup array.
