Removed old code intended to check the Geode parent of a Drawable to see if it's CullingActive is true as this was broken by the change osg::Drawable being derived from osg::Node rather than osg::Object.
pushModelViewMatrix or pushProjectionMatrix will already keep the
reference when adding it to the MatrixStack. In CullVisitor::apply
methods for the billboard and the camera you already take a pointer
instead of a ref_ptr."

- Added apply(Drawable) and apply(Geometry) to NodeVisitor
- Added accept(NodeVisitor) method to Drawable/Geometry
- Added traverse(NodeVisitor) to Geode which calls accept(NodeVisitor) on all Drawables
- Updated CullVisitor to use new apply(Drawable) to handle drawables. The apply(Billboard) method still manually handles the drawables since it is depends on the billboard settings. I needed to disable the traverse within billboard to prevent duplicate traversal of drawables.
- Update other osgUtil node visitors (GLObjectsVisitor, IncrementalCompileOperation, ..) to use new apply(Drawable) method.
"
The osgUtil::CullVisitor class will display an OSG_INFO notification when attempting to clamp the projection matrix with invalid near/var values. This usually appears when the scene graph is empty or all objects are culled. I don't think this scenario warrants having this message appear every frame. It makes it very difficult to debug other issues when this notification floods the output window.
I'd prefer to have the notification removed, but there might be legitimate cases where you want this displayed. Instead, I just disabled the output if the near/far values are equal to FLT_MAX (their initial values). This should at least prevent the notification for the common case where everything was culled."
Added COMPUTE_NEAR_FAR_USING_PRIMITIVES option that provides the original functionality where only the near plane
is computed in a fine grained way, with the far plane being computed simply from bound volumes.

* Change OcclusionQueryNode::getPassed to take a NodeVisitor rather than the distance from BS center to the eye point. Change where CullVisitor calls this method to use the new parameters.
* getPassed now exits early and returns true to avoid blinking / blink-in of geometry for the first frame or for out-of-range LOD children coming back into view.
* getPassed now considers the distance from the near plane to the bounding sphere (rather than eye point to bounding sphere) when determining if the viewer is "inside" the bounding sphere or not."
Note from Robert Osfield, I've temporarily re-enabled the old focing of of color and depth attachment to avoid regressions on some OpenGL driver. We'll revist this once
we have a mechanism for controlling this override at runtime.

#define FORCE_DEPTH_ATTACHMENT 1
via StateSet::setNestedRenderBin(bool) whether the new RenderBin should be nested
with the existing RenderBin, or be nested with the enclosing RenderStage.
