Convert a 4-channel sampling buffer into the picker colorspace.

GUI sampling must never rewrite live pixelpipe cachelines. When the picker needs a colorspace conversion, we therefore copy the denoised sampling buffer into a disposable external cache allocation and overwrite that private copy in place. The conversion keeps the alpha slot untouched because some callers reuse channel 3 for auxiliary picker statistics.
