modifying the mask to turn off planes which wouldn't contribute to clipping

of any internal objects. This feature is used in osgUtil::CullVisitor

to prevent redundant plane checking.

<DD>Transform the clipping set by matrix. Note, this operations carries out
|
|
the calculation of the inverse of the matrix since to transforms
|
|
planes must be multiplied my the inverse transposed. This
|
|
make this operation expensive. If the inverse has been already
|
|
calculated elsewhere then use transformProvidingInverse() instead.
