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

Found in the join file the fix for the bug found by Rafa.
Problem :
osgIntrospection::Value grp(new osg::Group);
osgIntrospection::ValueList vlcall;
vlcall.push_back(osgIntrospection::Value("toto"));
const osgIntrospection::MethodInfo *m =
grp->getType.getCompatibleMethod("setName", vlcall, true);
if (m)
{
m->invoke(grp, vlcall); // ** SEGFAULT here
}
Algorithm explanation :
The "invoke" method try to convert "grp", which reflect an
"osg::Group*", in a
"osgIntrospection::Value", which reflect a "osg::Node*".
This because
the "setName(const char *)" method found by
"grp->getType.getCompatibleMethod"
is an "osg::Object" type method.
When osgIntrospection do this conversion it try :
- to found a "osgIntrospection::Converter" to convert
from "osg::Group*" to "osg::Node*"
- to found a chain of "osgIntrospection::Converter" to convert
from "osg::Group*" to "one or many type" to "osg::Node*"
- to converte an Enum to int or unsigned int
- to convert the value in its "value string representation",
then converte this string in the destination value
Else it throw a "TypeConversionException".
Bug :
1)
When osgIntrospection try to found a chain of
"osgIntrospection::Converter"
It could do any downcast or (Type to SuperType) or upcast
(SuperType to Type).
This mean the the chain could be :
osg::Group to osg::Transform to osg::Camera to
osg::CullSettings to osg::CullStack to
osg::CollectOccludersVisitor to
osg::NodeVisitor to osg::Referenced to osg::Object
During the convertion with this chain, A METTRE failed and
the pointer in
"grp" is set NULL. But the "grp" is always a valid
"osgIntrospection::Value"
and so, osgIntrospection accept the conversion. Then it try
to use this pointer
to call the "setName" function. And Bing SEGFAULT.
2)
In "bool Reflection::accum_conv_path( ... )"
the convection path isn't accumulate in the recursive loop.
this cause multi request of a conversion path, and a
slowdown in the
conversion algorithm.
3)
Use of the last conversion way in a conversion from
pointer to pointer
this mean you can do this :
"osg::Node*" to " value string representation" to "osg::Material*"
What a bad thing !!!
Solution :
1)
Introduce the concept of dynamic_cast and static_cast.
now, to do a conversion, osgIntrospection does this :
- to found a "osgIntrospection::Converter" to convert
from "osg::Group*" to "osg::Node*"
- to found a chain of "osgIntrospection::Converter" to convert
from "osg::Group*" to "one or many type" to "osg::Node*"
only with static_cast, downcast (Type to SuperType)
- to found, if the source and the destination are two pointer,
a chain of "osgIntrospection::Converter" to convert
from "osg::Group*" to "one or many type" to "osg::Node*"
only with dynamic_cast, upcast (SuperType to Type)
- to convert an Enum to int or to unsigned int
- to convert the value in its "value string representation",
then convert this string in the destination value
Else it throw a "TypeConversionException".
Add the "enum CastType" to distinguish the static_cast or
dynamic_cast converter.
Add file OpenSceneGraph/include/osgIntrospection/CastType
2)
add a line to accumulate converter in converter Path.
3)
add a line to check if source and destination are pointer.

Stephan: "attached you'll find some modifications to the GraphicsWindow-class and
their platform-dependant implementations.
The problem:
setWindowRectangle and setWindowDecoration do not update the
traits-object, so, if you call setWindowRectangle on a
not-realized-window it will open with another size when realized later.
getWindowRectangle reports possible wrong sizes if setWindowRectangle
called before.
My solution:
split the implementation in two parts:
GraphicsWindow::setWindowRectangle will update its traits-object and
call afterwards the virtual method setWindowRectangleImplementation
(which is implemented by the derived platformspecific classess). For
setWindowDecoration I am useing a similar mechanism.
I hope you'll find the submission useful, the Win32 and X11 changes are
not tested but should work."
Changes to this made by Robert are call of resized in setWindowRectangle
instead of setting of Traits, and use of a bool return type.
changes I made:
+ put a warning in the console if a nonexistant screen is requested
+ add getters for the aglcontext and pixelformat -- I need access to
them in my own code.

the declaring file for a given type via the new member function
osgIntrospection::Type::getDeclaringFile. This information is useful
in order to know what header to include when auto-generating wrappers
for a given type.
During the C# wrapper generator development I've been keeping the
declaring file configuration state up-to-date manually with changes
to OSG, and it's proven to require substantial effort. So it would be
extremely valuable to get this change in before 2.0 to reduce maintenance
during the lifetime of the release. It'll also be equally useful to
others looking to create wrapper generators using osgIntrospection.
This is a fairly simple change and was tested with a fresh rebuild of the
entire suite of osgWrapper libraries, so it should be relatively low risk
(fingers crossed)."
