+
+  The preview strategy is as follows:
+  -----------------------------------
+
+   1) The preview is done on the full scan area or a part of it.
+
+   2) The preview is zoomable so the user can precisely pick
+      the selection area even for small scans on a large scan
+      surface.
+
+   3) The preview window is resizeable.
+
+   4) The preview scan resolution depends on preview window size
+      and the selected preview surface (zoom area).
+
+   5) We let the user/backend pick whether a preview is in color,
+      grayscale, lineart or what not.  The only options that the
+      preview may (temporarily) modify are:
+
+	- resolution (set so the preview fills the window)
+	- scan area options (top-left corner, bottom-right corner)
+	- preview option (to let the backend know we're doing a preview)
+        - gamma table is set to default (gamma=1.0)
+
+   5) The initial size of the scan surface is determined based on the constraints
+      of the four corner coordinates.  Missing constraints are replaced
+      by 0/+INF as appropriate (0 for top-left, +INF for bottom-right coords).
+
+   6) Given the preview window size and the scan surface size, we
+      select the resolution so the acquired preview image just fits
+      in the preview window.  The resulting resolution may be out
+      of range in which case we pick the minum/maximum if there is
+      a range or word-list constraint or a default value if there is
+      no such constraint.
+
+   7) Once a preview image has been acquired, we know the size of the
+      preview image (in pixels).  An initial scale factor is chosen
+      so the image fits into the preview window.
