<BLOCKQUOTE>Pure virtual base class for drawable Geometry. Contains no drawing primitives
directly, these are provided by subclasses such as osg::Geometry. State attributes
for a Drawable are maintained in StateSet which the Drawable maintains
a referenced counted pointer to. Both Drawable's and StateSet's can

<DD>Function to call to get the extension of a specified context.
If the Exentsion object for that context has not yet been created then
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
only be created with the graphics context associated with ContextID..

typically used when you have different extensions supported across graphics pipes

If the drawable has _useDisplayList set to true then use an OpenGL display
list, automatically compiling one if required.
Otherwise call drawImplementation().
Note, draw method should *not* be overridden in subclasses as it
manages the optional display list.
