4ab9c6f5f4 Removed check from objectDeleted(void*) method as this was not catching cases 
where the registered ptr was different from the deleted ptr - something that
can happen with multiple inheritance.

3016deaba9 From Paul de Repentigny, "When calling osgdem with argument "--image-ext", the application just 
returns after loading the proper ReaderWriter for the given extension."  Fix was to remove the erroenous return.

9c66cb4127 From Sylvan Marie, "I attached my revised dxfEntity.cpp file from the DXF plugin with the 2 
following improvements:

- When all unsupported entities (SOLIDS, TEXT, ...) have been filtered out
from a block, dxfInsert::drawScene() was crashing because it assumed that
the block was not empty. It now returns silently so the other blocks can
still be imported.

- The DXF reader assumed all vertices were read first, then the face
indices. But, from the DXF "documentation" (www.autodesk.com/dxf) :
"Polyface meshes created with the PFACE command are always generated with
all the vertex coordinate entities first, followed by the face definition
entities. The code within AutoCAD that processes polyface meshes requires
this ordering. Programs that generate polyface meshes in DXF should generate
all the vertices then all the faces. However, programs that read polyface
meshes from DXF should be tolerant of odd vertex and face ordering."
So now the importer ignores the posted number of vertices and face indices,
and uses the size of the lists instead."

30ad811cac From Eric Wing, add use of the autodetection of windowing size support in SDL-version 1.2.10 and later. 
From Robert Osfield, made the above an optional compile as it breaks apps based on previous version of SDL.

0c6a05392b From Mathias Froehlich, "Improovments: 
- does proper edge detection with the crease angle given in the ac file
- the reader is much more verbose in case of broken files
- no more static variables
- std::stream based
- much faster, up to a factor of 50 for a polygonal test model
- if the file contains polygonal surfaces the loaded geometry is still
polygonal as long as the polygons are convex. Concave polygons are still
tesselated. Rationale: If the user needs triangular models he can throw away
that extra information with the osgUtil::Optimizer himself. But the read step
preserves as much extra information that is contained in the file as
possible. Also the polygonal models look a bit smoother than the triangular
ones.
- a huge cleanup
- the basic parsing logic from the original ac3d developer is untouched
- the writer part is untouched

The tarball contains a replacement for the src/osgPlugins/ac3d directory that
is based on the current CVS (2006-11-13).
I have tested that loader with a osgconv foo.ac /tmp/xx.ive on everyfoo. ac
file I could find (~200 from flightgear and the object database). I also run
my flightgear development with that loader -> here I see the models.
I run valgrind testcases on some selected models."

b5bb541cca From Stephan Huber, Follows is required to prevent unidented cloning of shared arrays : 
"I added some calls to isOperationPermissibleForObject() so I can permit the flattten-pass with my specialized objects in my own code."

7cb1bcbd7d From Farshid Lashkari, "This patch adds a CoordOriginMode to the osg::PointSprite attribute. 
The mode needs to be changed to LOWER_LEFT when rendering point
sprites to pbuffers or FBOs, otherwise the points will be transformed
on the CPU."
