Note, this required adding a unsigned int context ID to the osg::isGLUExtensionSupported(,)
and osg::isGLExtensionSupported(,) functions. This may require reimplementation
of end user code to accomodate the new calling convention.
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.
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.
and a fix to osg::State's secondary color code from Bob Kuehne.
Moved the body of the getGLExtensionFuncPtr() into the header to help out
support for Windows mapping of different OpenGL extensions function ptr per
dll.
