Resize any per context GLObject buffers to specified size.

Reimplemented from osg::Object.

Reimplemented in osg::PixelDataBufferObject.

void osg::BufferObject::setBufferData ( unsigned int  index,
BufferData bd 
)
void osg::BufferObject::setCopyDataAndReleaseGLBufferObject ( bool  copyAndRelease)
inline

Set whether the BufferObject should use a GLBufferObject just for copying the BufferData and release it immmediately so that it may be reused.
