handle scenes with multiple views with elements that need coordinating on a per view basis.
Added beginings of new osgText::FadeText class (not functionality yet).

is the fastest option since checking for errors does incurr a small overhead.*/
NEVER_CHECK_GL_ERRORS,

frame, the overhead is still small, but at least OpenGL errors that are occurring
will be caught, the reporting isn't fine grained enough for debugging purposes.*/

every attribute is applied, allow errors to be directly associated with

support for the unsigned int member to be paired with types in osg::StateSet
so that lights, clipplanes and other attributes that have a type group but
then need to differentiate within that group via a member uint.
the state stack, thus readying the state object to recieve a new frame.
Removed the state.reset() call in osgUtil::SceneView::cull() as this was
causing problems with stats producing inheritance of state when toggling
stats on.
part of prep for supporting both Matrixf (float) and Matrixd (double).
Added osg::Matrixf::glLoadMatrix() and osg::Matrixf::glMultiMatrix() methods
and changed corresponding usage of glLoad/MultMatrixf() calls across to use these
methods. Again prep for support Matrixd.
Fixes for VisualStudio 6.0 compile.
by osgUtil::RenderLeaf to test if any abort state has been set, if so it
doesn't do any further drawing.
The osgProducer::Viewer has been set up to set the osg::State's it manages
with their AbortRendering flag pointers set to the osgProducer::Viewer::_done
memeber varaible. Now when escape is pressed the rendering is aborted early.
that they arn't created on the stack inappropriately.
Split the implemention of Matrix up so that it is a simple no referenced counted
class and can be safefly created on the stack. To support referenced counting a
seperate subclass now exists, this is RefMatrix which inherits from both Matrix and
Object.
Added new osg::State::setInterleavedArray() method.
Added new osg::Group::setNode(uint,Node*) method.
Cleaned up and fixed the osg::Texture's handling of dirtyTextureParamters().
code which modifies the OpenGL state and needs to tell the osg::State
about it to ensure that the OSG doesn't make any errors during lazy
state updating.
