To facilitate this possibility I have added a template copy constructor and a template assignment operator. These work for safe conversions like those in my previous example, but fail as desired for non-safe conversions since the template instantiation fails during the raw pointer copy/assignment.
The lack of this facility has appreciably handicapped development of generic algorithms applied to the scene graph, and I believe that this alteration will be welcomed by most of the community. If there are issues with antiquated compilers not supporting template member functions then perhaps a small piece of conditional compilation is in order.
I have made the change using the latest release version (2.6) as the base. The full file is attached.
I have not tested building the osg wrappers and the script binding code. I have tested the legal and illegal conversions of both copying and assignment to ensure that behave as expected on MSVC7.1, MSVC8, MSVC9, GCC 4.3."
Quicktime supports only files with 3/4-channels rgba-files and not 1/2-channels rgb-files.
This submission is from Tatsuhiro Nishioka, here's his original quote:
When FlightGear crashes, the error message
"GraphicsImportGetNaturalBounds failed" shows up. By adding printf
debug, I found the error was -8969: codecBadDataErr when loading a
gray-scaled (2 channels) rgba files even though the file can be loaded
with Gimp and osgViewer properly.
So I made an investigation on this problem and found an interesting
thing. This error occurs only when non-rgb files are loaded before rgb
files. The reason is that rgba files can be handled by both
osgdb_rgb.so and osgdb_qt.so, but the error happens only when
osgdb_qt.so try to load a gray-scaled rgba file.
When a program is about to load an rgba file, osgdb_rgb.so is loaded
and it handles the rgba file properly. In contrast, when a gray-scaled
rgb file is being loaded after a non-rgb file (say png) is already
loaded by osgdb_qt.so, osgdb_qt.so tries to load the file instead of
osgdb_rgb, which causes the error above.
Anyway, the bad thing is that QuickTime cannot handle gray-scaled rgb
files properly. The solution for this is not to let osgdb_qt handle
rgb files since osgdb_rgb can handle these properly.

This code will add two extra statistics options:
-Camera scene statistics, stats for the scene after culling (updated at 10 Hz)
-View scene statistics, stats for the complete scene (updated at 5 Hz)
Each camera and each view will expand the statistics to the right.
I also added the requests and objects to compile of the databasepager to the databasepager statistics.""
Attached is a change that is able to provide shared textures for the clamp and
the repeat case.
So this appears to be the best fix I guess ...
Also it additionaly shares the TexEnv StateAttribute in a whole ac3d model."
..\..\..\..\src\osgDB\Registry.cpp(910) : warning C4806: '==' : unsafe operation: no value of type 'bool' promoted to type 'osgDB::Registry::LoadStatus' can equal the given constant
A quick review of the code revealed a piece of code that was clearly wrong, possibly due to a copy-and-paste error.
