* (3) The 4 flags determine whether the sel is increased on that side

* (2) No elements are selected that are less than 'distance' pixels away
* from a boundary pixel of the same color. This makes the
* match much more robust to edge noise. Valid inputs of
* 'distance' are 0, 1, 2, 3 and 4. If distance is either 0 or

* can be use if the pattern is expected to be surrounded by bg
* (white) pixels. On the other hand, if the pattern may be near
* other fg (black) components on some sides, use 0 for those sides.
* (4) The pixels added to a side allow you to have miss elements there.
* There is a constraint between distance, minlength, and
* the added pixels for this to work. We illustrate using the
* default values. If you add 5 pixels to the top, and use a
* distance of 1, then you end up with a vertical run of at least
* 4 bg pixels along the top edge of the image. If you use a
* minimum runlength of 3, each vertical line will always find
* a miss near the center of its run. However, if you use a
* minimum runlength of 5, you will not get a miss on every vertical
* line. As another example, if you have 7 added pixels and a
