The Texture Pool can be enabled by setting the env var OSG_TEXTURE_POOL_SIZE=size_in_bytes.
Note, setting a size of 1 will result in the TexturePool allocating the minimum number of
textures it can without having to reuse TextureObjects from within the same frame.
Note from Robert Osfield, I've temporarily re-enabled the old focing of of color and depth attachment to avoid regressions on some OpenGL driver. We'll revist this once
we have a mechanism for controlling this override at runtime.

of these methods in src/osgViewer/Renderer.cpp to make sure that the draw thread keeps references to all in scene graph Cameras
that are being used by the drawing threads, to keep the Camera's alive even when the main thread removes these Cameras from the scene graph.
osg::ColorMask* leftColorMask = _renderStageLeft->getColorMask();
if (!leftColorMask)

^^^^ here it said right, I think this should be Left.

// ensure that right eye color planes are active.
osg::ColorMask* rightColorMask = _renderStageRight->getColorMask();

and i further removed an unnecessary setColorMask."
The vertical separation not actually displayed as it is set. So some
display the up and down stereo images style will not be correct.
Someone may forget to change the "Horizontal" to "Vertical" after
copying and pasting the code from above HORIZONTAL_SPLIT code segment.
I've attached the file. By replacing the incorrect "Horizontal" to
"Vertical", the bug is gone.

use the osg::State::applyMode for enabling/disabling certain while
rendering the stencil mask. Previously some of these calls were
overriding the scene graph states because the global state was not
aware of this change.

viewport settings in stereo mode. It seems that the SceneView::cull()
method will pass the full size viewport to the left/right
cullvisitors, instead of the modified stereo viewport. I made quite a
few changes to SceneView to fix the issue. The SceneView::cullStage()
method will now receive the viewport as an argument, instead of using
the global viewport. The SceneView::cull() method will pass the
modifed viewport to cullStage when rendering in stereo.
There are 2 new private methods computeLeftEyeViewport() and
computeRightEyeViewport() that will compute the stereo viewports. I
also modified the draw() function so it applies the correct viewport
to the prerender stages. These changes are only necessary for
horizontal/vertical split stereo."

stereo format to work. It's a good thing I tested these on a TV
before submitting them since I did indeed have a bug. One thing I
did not test was to see how this would work in windowed mode. Does
the interlaced stereo code have support for 'absolute' positions?
For example a given pixel on the screen is always shown in a given
eye no matter where the graphics context is placed?

Added and cleaned up DeleteHandler calls in osgViewer to help avoid crashes on exit.
Changed DatabasePager across to dynamically checcking osg::getCompileContext(..)
Updated wrappers.
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.
