This function has several different purposes and thus has several synonyms. It copies one GpuMat to another with optional scaling, which is performed first, and/or optional type conversion, performed after: dst(I)=src(I)*scale + (shift,shift,...) All the channels of multi-channel GpuMats are processed independently. The type conversion is done with rounding and saturation, that is if a result of scaling + conversion can not be represented exactly by a value of destination GpuMat element type, it is set to the nearest representable value on the real axis. In case of scale=1, shift=0 no prescaling is done. This is a specially optimized case and it has the appropriate convertTo synonym.
