Have added a #define USE_DEPRECATED_API to include/osg/Export, and various osg header and source files to optional compile in deprecated parts of the OSG API. Have renamed osg::Transparency osg::BlendFunc to bring it in line with the rest of the OSG's StateAttribute classes which are named after their OpenGL counterparts. include/osg/Transparency still exists and is simply a typedef to BlendFunc and is enclosed in a #ifdef USE_DEPRECTATED_API block. The matrix methods in the osg::Transform class have been moved/replicated in a osg::MatrixTransform sublcass from osg::Transform. The old matrix functionality is still present in the osg::Transform class but is guard by #ifdef USG_DEPRECATED_API blocks. One should now think of osg::Transform as being a Transform Node base class. MatrixTransform has all the functionality of the original Transform class, so should be used instead. 2002-07-12 22:25:10 +08:00			`// define used to include in API which is being fazed out`

Added support for osg::MemoryManager which is based upon Paul Nettle's memory manager published at flipcode.com. This can be turned on with the OSG_USE_MEMORY_MANGER option which then uses custom global new and delete operators as well as provide osgNew and osgDelete macro's which add ability to log line and file from which calls are made. Updated osg,osgUtil,osgDB,osgText and osgPlugins/osg to use osgNew/osgDelete, and fixed memory leaks highlighted by the new memory manager. 2002-03-27 07:52:52 +08:00			`#include <osg/MemoryManager>`
