It adds two options:
Accuracy(x) - ensures the polyline will be within x units from the ideal arc/curve
ImproveAccuracyOnly - do not use the given accuracy 'x', if it would result in a worse curve than with the previous (2.8.0) implementation for a particular arc/curve.
As an added bonus there was a small bug in the existing implementation whereby the primitives were line strips but the vertices generated were actually suitable for GL_LINES, so the improved accuracy doesn't even have to come at a performance cost :-)"
-Added copying of shaders and attributes in osg::Program copy constructor.
-Changed StateSet::compare function to compare Uniforms and their
override values. Previously it compared a RefUniformPair."
The problem is in SpatializeGroupsVisitor::divide(osg::Geode*, unsigned int) where the code creates a new Group and divides up the input Geode into one Geode per Drawable.
I fixed the problem by assigning the Geode's stateset to the new parent group.
To replicate the bug, see attached osg/dds files:
osgviewer b.osg -- model renders correctly
set OSG_OPTIMIZER="SPATIALIZE_GROUPS"
osgviewer b.osg -- textures are missing."
to make is easier to write code that can work on DrawElementUByte, UShort or UInt.
Changed the osgTerrain::GeometryTechnique so that it automatically chooses
the use of DrawElementUShort or DrawElementsUInt accordining to the size of the tile.

It expects 'src_pix_fmt' and 'dst_pix_fmt' to be of type 'PixelFormat' rather than int. The attached cast fixes this (for me).
I've also added Matroska video to the list of supported extensions"
Please look at the .diff files for details. I have already enjoyed the latest Chinese *big* movie "Red Cliff" with the fixed ffmpeg plugin and osgmovie. :D"

avoid possible trouble, gcc warns about this. Attached modification
fixes the initializer order to silence this warning."
Also, there was also a small bug in osgDB's CMakeLists.txt that was causing an error when I tested with CMake 2.4.4.

Very simple cases of state configuration are supported (all the ones I really need):
- single per pixel not attenuated non spot light source ON/OFF
- exp2 fog ON/OFF
- diffuse texture in rgb + optional specular gloss in alpha (Texture unit 0) ON/OFF
- normal map texture (Texture unit 1 and Tangent in VertexAttribArray 6) ON/OFF
- blending and alpha testing (not in shader pipeline)
To view fixed function pipeline files and paged databases simply run >osgshadergen myfile.osg"
the filename extension is "vert" or "frag" but still lets this be
overridden by the Options (for those crazy people who store their
fragment shaders in .vert files :) )."
ADD_LIBRARY(${TARGET_TARGETNAME} MODULE ${TARGET_SRC} ${TARGET_H})
which gives them .so extensions. Since ".so" != ".dylib" osgDB::listAllAvailablePlugins finds no plug-ins. I believe the correct solution is to use CMAKE_SHARED_MODULE_SUFFIX instead. This builds and runs correctly on OS X but I have not tested on other platforms.
Attached is an updated src/osgDB/CMakeLists.txt based on rev 9915. The change is at line 108. To validate: build and then run bin/osgconv --formats. You should get many screenfuls of plug-in features, extensions and options."
