* Given OverlayOp funx code enum a name and renamed values to have a lowercase prefix. Drop all of noding headers from installed header set.
*
* Revision 1.1 2006/03/17 13:24:59 strk
* opOverlay.h header splitted. Reduced header inclusions in operation/overlay implementation files. ElevationMatrixFilter code moved from own file to ElevationMatrix.cpp (ideally a class-private).
