Function to call to get the extension of a specified context.

If the Extension object for that context has not yet been created and the 'createIfNotInitalized' flag been set to false then returns NULL. If 'createIfNotInitalized' is true then the Extensions object is automatically created. However, in this case the extension object is only created with the graphics context associated with ContextID..

void osg::GLBufferObject::setBufferObject ( BufferObject bufferObject)
static void osg::GLBufferObject::setExtensions ( unsigned int  contextID,

) [static]

setExtensions allows users to override the extensions across graphics contexts.

typically used when you have different extensions supported across graphics pipes but need to ensure that they all use the same low common denominator extensions.
