Added setting of osg_SimulationTime and osg_DeltaSimulationTime to the uniforms set by SceneView
Added frame(double simulationTime) and advance(double simulationTime) parameters to
osgViewer::SimpleViewer, Vewer and CompositeViewer.
Updated various examples and Nodes to use SimulationTime where appropriate.
keyboard and mouse events.
Added osgGA::EventQueue class to support a thread safe event queue and adaption
of keyboard and mouse events.
Removed osgProducer::EventAdapter as GUIEventAdapter replaces it.
Adapted osgProducer and examples to work with the new changes to osgGA.
leaving it up to the Viewer to specify the mode (which by default is MultiThreaded).
Added a check for the presence of osgParticle systems so that threading is
disabled in this case.
o Object files now go in subdirectories named $(OS)$(ARCH).Opt and
$(OS)$(ARCH).Debug for OS's that support both architectures.
eg. Linux32.Opt and Linux32.Debug
o Libraries links are now placed in lib/$(OS)$(ARCH)
eg. lib/Linux32/
o Binaries are now placed in bin/$(OS)$(ARCH)
eg. bin/Linux32
o 'make install' and 'make instlinks' now place files/links in
/usr/local/{include,lib,share/OpenSceneGraph} by default on
most systems (Solaris still goes in /opt/OpenSceneGraph).
Rather than having the somwehat confusing INST_SYS_PREFIX and
INST_SHARE_PREFX, you can override these with just
INST_LOCATION
For example,
make INST_LOCATION=/usr
will place files at /usr/include, /usr/lib,
/usr/share/OpenSceneGraph.
2) Changed Makedepend system to make individual dependency files, which
should save time rebuilding dependencies by limiting the regeneration
of dependency file for only modified source files.
osg::Image::setImage has also been modified to require the AllocationMode
mode to be passed to it so that it knows how to delete the data once the
image goes out of scope.
Port the image plugins across to specify the new AllocationMode, and converted
them across to using new/delete in place of malloc/free.
