I realized, this may work to some extent for gradients and other such<br>
areas of varying pixel values, but it won’t properly handle areas of<br>
constant colour. Averaging 4 or 16 pixels of the same truncated value is<br>
not going to recover the original, more accurate value.<br>
<br>
Still, it might be of use with photorealistic-type imagery...<br>
