This functions has been renamed into DetectSmoothImage recently. It
tries to analyze statistical properties of the image. If intensity of
color components change smoothly within neighbouring pixels, then
tight encoder tries to improve compression either compressing
differences (deltas) between pixels, or using JPEG coder if enabled by
user.
