Replacing Graphics Object shouldnrequires manual call of ReleaseGraphicsResources
The required calling of ReleaseGraphicsResources when graphics object i.e: Actor, Mapper, Texture et al in order to prevent application from crashing. This issue has a lesser occurrence with OpenGL1 which by default uses the immediate rendering mode compared to GL2. This prerequisite of having to track and manually release these objects can be done internally without having to delegate the task to developers.
