Draws the custom primitive.
The primitive is drawn in the scene directly using OpenGL calls. The coordinates are set to the local space of the custom primitive object. Use GL_LINES or GL_LINE_STRIP to define the outline of the object. The plugin should not change the OpenGL states on exiting the callback.
CStatus <plugin-item_name>_Draw( CRef& in_context )
{
        ...
}

<plugin-item-name> is the name specified in the call to PluginRegistrar.RegisterPrimitive with any spaces converted to underscores. For example, if you register a primitive with the name "My Primitive", the callback function names start with "My_Primitive".
