+<p>Create a selection by selecting all pixels around specified

+coordinates.</p>
+<p>This tool creates a contiguous selection over the specified image. A
+contiguous color selection is determined by a seed fill under the
+constraints of the current context settings. Essentially, the color
+at the specified coordinates (in the drawable) is measured and the
+selection expands outwards from that point to any adjacent pixels
+which are not significantly different (as determined by the
+threshold and criterion context settings). This process continues
+until no more expansion is possible. If antialiasing is turned on,
+the final selection mask will contain intermediate values based on
+close misses to the threshold bar at pixels along the seed fill
+boundary.</p>
