optimizations to reduce cpu overhead:
1) Avoid a load-hit-store in UpdateBone. b->getMatrixInBoneSpace()
returns the same matrix that was just stored with b->setMatrix()
2) Avoid calling element->isIdentity() for the whole transform stack
(can be expensive is element is a matrix)
3) Make the key frame interpolator use binary search instead of a
linear one. This is very noticeable in scenes where some geometry has
long repeating animations that start at the same time, you will see
the update time grow then reset and grow again."

Initially I described issue in message:
http://forum.openscenegraph.org/viewtopic.php?t=13820
It solves issue with compiling texture using ico from image with mipmaps
I added enviroment variable OSG_GL_TEXTURE_STORAGE_ENABLE to control usage of glTexStorage2d. Initially it is disabled.
It used only if image have mipmaps.
Another issue is converting from internalFormat + type to sized internal format. I created sizedInternalFormats[] struct where sized internal formats are ordered from worse->best.
also this struct have commented lines. Commented formats are listed in
http://www.opengl.org/wiki/GLAPI/glTexStorage2D
but looks like not using in osg."
Note from Robert Osfield. Changed the env var control to OSG_GL_TEXTURE_STORAGE and made it's value true by default when the feature is supported by the OpenGL driver. To disable to
use of glTexStorage2D use OSG_GL_TEXTURE_STORAGE="OFF" or "DISABLE"

If Drawable::getBoundingBox would compute an invalid bounding box (if it was for example empty) it would make a bounding sphere with a infinite radius which counts as a valid sphere in osg.
Attached is a small fix."
- Added apply(Drawable) and apply(Geometry) to NodeVisitor
- Added accept(NodeVisitor) method to Drawable/Geometry
- Added traverse(NodeVisitor) to Geode which calls accept(NodeVisitor) on all Drawables
- Updated CullVisitor to use new apply(Drawable) to handle drawables. The apply(Billboard) method still manually handles the drawables since it is depends on the billboard settings. I needed to disable the traverse within billboard to prevent duplicate traversal of drawables.
- Update other osgUtil node visitors (GLObjectsVisitor, IncrementalCompileOperation, ..) to use new apply(Drawable) method.

ran into two issues.
At first you get a bunch of warnings that osg::ComputeBoundCallback
and osg::UpdateCallback were unsupported wrapper classes when
converting fbx models with skeletal animation to osg(t/b).
The second issue was that when reading, the readers fail to read the
ComputeBoundCallback and UpdateCallback and set them to NULL which
messes up the RigGeometry.
Because a RigGeometry makes his own classes in the constructor it
might be preferable to not write them at all, because now those
classes are being made two times when reading a RigGeometry. But after
thinking about this that would place too much limits on them (you
won't be able to share or name them and save that information or make
a new inherited class from them and write that one) So I ended up
thinking the best way was to just write the files.

attributes in vec3b format. It looks like my compiler takes the wrong
overload and outputs integers instead of characters. The problem is
that vec3b is of type signed char and that is not the same as char (
see http://stackoverflow.com/questions/436513/char-signed-char-char-unsigned-char
) and visual studio 2013 will promote it to integer when choosing an
overload.
It looks like that the InputStream class already takes care of this
issue (if it didn't it would have read everything ok and I would have
not even stumbled upon this bug. :) )"
There was code in the osgViewer/Viewer.cpp and osgViewer/CompositeViewer.cpp that transformed the Y-coordinates of an event. The code in the composite viewer did however miss the touch-data of the event. I thought that it should really be the GUIEventAdapter that should know about this, and hence I added the
GUIEventAdapter::setMouseYOrientationAndUpdateCoords which is re-computing the coordinates. First I simply added a boolean to the setMouseYOrientation function:
setMouseYOrientation( MouseYOrientation, bool updatecooreds=false );
but then the serializer complained.
This function is called from both the Viewer and the CompositeViewer. We have not tested from the viewer, but I cannot see it would not work from visual inspection.
The other change is in MultiTouchTrackballManipulator::handleMultiTouchDrag. I have removed the normalisation. The reason for that is that it normalised into screen coordinates from 0,0 to 1,1. The problem with that is that if you have a pinch event and you keep the distance say 300 pixels between your fingers, these 300 pixels represent 0.20 of the screen in the horizontal domain, but 0.3 of the screen in the vertical domain. A rotation of the pinch-fingers will hence result in a zoom in, as the normalised distance is changing between them.
A consequence of this is that I have changed the pan-code to use the same algorithm as the middle-mouse-pan.
The rest of it is very similar from previous revision, and there has been some fine-tuning here and there.

To select standard OpenGL 1/2 build with full backwards and forwards comtability use:
./configure
make
OR
./configure -DOPENGL_PROFILE=GL2
To select OpenGL 3 core profile build using GL3/gl3.h header:
./configure -DOPENGL_PROFILE=GL3
To select OpenGL Arb core profile build using GL/glcorearb.h header:
./configure -DOPENGL_PROFILE=GLCORE
To select OpenGL ES 1.1 profile use:
./configure -DOPENGL_PROFILE=GLES1
To select OpenGL ES 2 profile use:
./configure -DOPENGL_PROFILE=GLES2
Using OPENGL_PROFILE will select all the appropriate features required so no other settings in cmake will need to be adjusted.
The new configuration options are stored in the include/osg/OpenGL header that deprecates the old include/osg/GL header.
Using the trunk together with osgEarth 2.5 will fail to build, due to the missing type.
Attached is the file forward declaring osgGA::GUIEventAdapter."
osg/GL2Extensions was incorrectly defining GL_RED_SNORM and GL_RG_SNORM as part of the definitions for OpenGL v3.1. However, a quick review of the 3.1 spec indicates that these are not part of the 3.1 standard.
My attached change moves these definitions out of the #ifndef GL_VERSION_3_1 conditional block, and defines them conditionally if not already defined. This allows the DDS plugin to build for GL3.

To the Lua plugin added support for assigned lua functions to C++ osg::Objects via the new osg::CallbackObject mechanism. To invoke the scripts function from C++ one must get the CallbackObject and call run on it.
Renamed ScriptCallback to ScriptNodeCallback to avoid possibly confusion between osg::CallbackObject and the ScriptNodeCallback.
One solution is naturally to create a new class that would inherit the osg::ComputeBoundVisitor, and use that. I don't like that idea as the ComputeBoundVisitor does actually have what I need - it is only hidden in a protected function.
I am therefor suggesting a slight generalization of the ComputeBoundVisitor with the attached patch, which is tested.
The patch has two parts:
we add applyBBox() so that one can use that in a customized traverse-function and add a bbox to the visitor. I considered calling this function expandByBBox(), but I though applyBBox was better.
The MatrixStack is made available to the outside world. That enables a traverse-function to do whatever it wishes.
I do actually only need one of the two, as I can implement what I wish either way, but adding getMatrixStack() will make more generic expansions possible.
"
From Robert Osfield, changed the name of the new applyBBox(..) method to applyBoundingBox(..) to keep it's naming more consistent with the rest of the OSG.
I added a new tag to p3d called forward_touch_event_to_device and renamed the existing forward_event_to_device to forward_mouse_event_to_device. This new tag will transmit touches to the virtual trackpad as touch events. I added the MultitouchTrackball to the p3d-app so zooming and moving a model remotely should now work, if you use forward_touch_event_to_device. I kept (and fixed) forward_mouse_event_to_device for background compatibility, so old presentations works as in previous versions, without the ability to zoom + scale. of course.
forward_touch_event_to_device needs some more testing, (e.g. with image-streams and keystone, afaik there’s no support for touch-events...) but for a first version it works nice.

From Robert Osfield, changed Roni's code to use a #define GETDEVICEPIXELRATIO to access the versioned Qt devicePixelRatio() method to avoid duplication of the Qt version checking.
