+
+	* From Panagiotis Papadakos, "Setting the maximum height of osgText
+	  doen't seem to work. If the text is big enough, it exceeds the
+	  height that I gave as input to setMaximumHeight. So check if
+	  cursor is out of -_maximumHeight."
+
+	* Added support for defining an option
+	  OSG_GLU_TESS_CALLBACK_TRIPLEDOT within the CMake build system,
+	  enabling this option will build the OSG against the (...) version
+	  of the tesselation callback functions. One can also set the
+	  default value of this option via the
+	  DEFAULT_GLU_TESS_CALLBACK_TRIPLEDOT variable that is set locally
+	  to OFF for all platforms except AIX and OSX, but can be overriden
+	  by setting it via command line option i.e. cmake .
+	  -DDDEFAULT_GLU_TESS_CALLBACK_TRIPLEDOT=ON
