Take look of 4channels sample

Take look of 4channels sample in LibRaw/samples.
It works very simple
- it uses half-mode to fill all elements of image[] array (but the array is 1/4 of size, so every 4 bayer pixels are folded into one image[][4])
- it demonstrates access to image[][] elements for auto-scale
