If the number of data points to generate a "Horizontalschnitt" is above a given threshold, they are culled against an 5% extented bounding box of the interpolation area. gnv-artifacts/trunk@611 c6561f87-3c4e-4783-a992-168aeb5c3f6f

+	* src/main/java/de/intevation/gnv/math/AreaInterpolation.java:
+	  - The lastest refactoring removed the evaluation of the
+	    depth. Now its back in again. 
+
+	  - If the number of incoming points is greater than
+	    a given threshold (default: 1000) than the bounding box
+		of the interpolation is extend about 5% for a test
+		if the points are in this area. Points outside this
+	    area are culled because its unlikely that they have
+		any influence on the result. Use the system property
+		"gnv.areainterpolation.cull.point.threshold" to modify
+		the threshold value.
+
+	* src/main/java/de/intevation/gnv/math/GridCell.java: When
+	  build the interpolation areas the points are culled against
+	  extented bounding box.
