<DD>Set the current OpenGL context uniqueID.
Note, it is the application developers responsibility to
set up unique ID for each OpenGL context. This value is
then used by osg::StateAttribure's and osg::Drawable's to
help manage OpenGL display list and texture binds appropriate
for each context, the contextID simply acts as an index local
arrays that they maintain for the purpose.
Typical settings for contextID are 0,1,2,3... up to the maximum
number of graphics contexts you have setup.
By default contextID is 0.
