readFontStream() to load fonts from a std::istream, rather than from the
local filesystem by name. Such a call may be used, for example, if the
user has a font fetched over a network, or a font available in memory
without a correspondng filename.
The changes implement the new function by following the corresponding code
for readFontFile(). readFontStream() reads a stream into memory, and
holds that memory for FreeType.
As a basic test, I mangled the osgtext example to use
readFontStream(std::ifstream("font")) in lieu of a readFontFile call, and
the modified example ran completely."
Drawables,StateSet, and osgDB::Registry.
Added cleanup_frame() from to osgProducer::OsgCamerGroup to help with proper
clean of OpenGL objects before exit, and modified osgviewer, osghangglider,
osgwindows examples to do the extra frame call to cleanup_frame() before exit.
the actual implemention. This has been done so that when a freetype font is
created the implementation can unloaded when the freetype plugin is unloaded
without breaking the main font.
Also add image margin around founds to prevent any image boundaries appearing.
any reference to these in the distribution across to using unsigned char,
unsigned short etc. This has been done to keep the OSG code more opaque
to what types are.
a fully functioning NodeKit.
Also reimplement notify() to try an prevent a crash which has been caused by
to objects in notify.cpp being initiliazed twice, the second time the auto_ptr
holding the dev/null ofstream was being initilized to 0.
copy constructor which takes an optional Cloner object, and the old
osg::Object::clone() has changed so that it now requires a Cloner as paramter.
This is passed on to the copy constructor to help control the shallow vs
deep copying. The old functionality of clone() which was clone of type has
been renamed to cloneType().
Updated all of the OSG to work with these new conventions, implemention all
the required copy constructors etc. A couple of areas will do shallow
copies by design, a couple of other still need to be updated to do either
shallow or deep.
Neither of the shallow or deep copy operations have been tested yet, only
the old functionality of the OSG has been checked so far, such running the
viewer on various demo datasets.
Also fixed a problem in osg::Optimize::RemoveRendundentNodesVisitor which
was not checking that Group didn't have have any attached StateSet's, Callbacks
or UserData. These checks have now been added, which fixes a bug which was
revealled by the new osgscribe demo, this related to removal of group acting
as state decorator.

Alas changed the indenting to use 4 spaces instead of tabs, this irons out
differences when working under Windows and Unix, keeping the identing
consistent.
