<BLOCKQUOTE>A Transform is a group node for which all children are transformed by
a 4x4 matrix. It is often used for positioning objects within a scene,
producing trackball functionality or for animation.
<P>Transform itself does not provide set/get functions, only the interface
for defining what the 4x4 transformation is. Subclasses, such as
MatrixTransform and PositionAttitudeTransform support the use of an
osg::Matrix or a osg::Vec3/osg::Quat resprectively.
The Transform node can be customized via the ComputeTransfromCallback
which can be attached to the node. This might be used to convert from
internal representations of the transformation into generic osg::Matrix
objects which are used during scene grpah traversal, such as
CullTraversal and IntersectionTraversal.
<P>Note: if the transformation matrix scales the subgraph then the normals
of the underlying geometry will need to be renormalized to be unit
vectors once more. This can be done transparently through OpenGL's
use of either GL_NORMALIZE and GL_SCALE_NORMALIZE modes. For further
background reading see the glNormalize documentation in the OpenGL
Reference Guide (the blue book). To enable it in the OSG, you simply
need to attach a local osg::StateSet to the osg::Transform, and set
the appropriate mode to ON via
stateset->setMode(GL_NORMALIZE, osg::StateAttribute::ON);</BLOCKQUOTE>

<DD>Set the transform's ReferenceFrame, either to be relative to its
parent reference frame, or relative to an absolute coordinate
frame. RELATIVE_TO_PARENTS is the default.
Note: setting the ReferenceFrame to be RELATIVE_TO_ABSOLUTE will
also set the CullingActive flag on the transform, and hence all
of its parents, to false, thereby disabling culling of it and
all its parents. This is neccessary to prevent inappropriate
culling, but may impact cull times if the absolute transform is
deep in the scene graph. It is therefore recommend to only use
absolute Transforms at the top of the scene, for such things as
heads up displays.

<DD>Overrides Group's computeBound.
There is no need to override in subclasses from osg::Transform
since this computeBound() uses the underlying matrix (calling
computeMatrix if required.)
