Detailed Description

template<class Traits>
class KisCrossDeviceColorSamplerImpl< Traits >

The sampler class is supposed to help to sample color from one device and automatically convert it to the color space of another device

WARNING: Please note, that if you want to access correct rawData(), you shouldn't store the sampler class (as well as any random accessor class) across different calls to paintAt. This is related to the fact that KisRandomAccessor has an internal cache of the tiles, but any tile may become 'old' with the time, so you'll end up reading from the old tile instead of current one.
