Perform the move of the pixels to the new orientation.

Copy three values for each iteration of the inner loop. This moves the red, green, and blue information.

The values of colorStride and yStride need to change because the dimensions of the image may have changed.

In this mode, we are moving an entire row at once. First all of the red rows are moved. Next, all of the green rows are moved. Lastly, all of the blue rows are moved. In mono mode, the outer loop only executes once.

In this mode, we are moving three rows at a time. All the red, green, and blue information for each for are moved at once.
