gpu::swapChannels
-----------------
Exchanges the color channels of an image in-place.

:param src: Source image. Supports only ``CV_8UC4`` type.
:param dstOrder: Integer array describing how channel values are permutated. The n-th entry of the array contains the number of the channel that is stored in the n-th channel of the output image. E.g. Given an RGBA image, aDstOrder = [3,2,1,0] converts this to ABGR channel order.

The methods support arbitrary permutations of the original channels, including replication.
