+================================================================================
++pcbnew
+  * surbrill.cpp's int WinEDA_PcbFrame::Select_High_Light( wxDC* DC )
+    was re-written to use the GENERAL_COLLECTOR, and the scanList is set to
+    give pads a higher search priority than tracks, vias or pads.
+    The objective was to use the pad if possible, rather than a track on a pad,
+    so the pad can be sent to eeschema.  Finding the track only (even though
+    on a pad) would not send anything to eeschema.
