+- applied fix for the foreground matting feature as suggested at bug #723818
+  The warning "Problem!: final_confidence: %f\n" now shall be printed only in critical case.
+
+  TODO: Note that GAP still uses a copy of the old foreground matting implementation
+  The already available GEGL implementation will be used in future GAP versions
+  targeted for the use with GIMP 2.10.
