Different ways to get the increments for moving around the data. incX is always returned with 0. incY is returned with the increment needed to move from the end of one X scanline of data to the start of the next line. incZ is filled in with the increment needed to move from the end of one image to the start of the next. The proper way to use these values is to for a loop over Z, Y, X, C, incrementing the pointer by 1 after each component. When the end of the component is reached, the pointer is set to the beginning of the next pixel, thus incX is properly set to 0. The first form of GetContinuousIncrements uses the active scalar field while the second form allows the scalar array to be passed in.
