annotate Framework/Scene2D/Internals/OpenGLColorTextureProgram.cpp @ 700:059e1fd05fd6 refactor-viewport-controller
Introduced the ViewportController that sits between the application and the
Scene2D to handle the trackers and measuring tools. This is a work in progress.
The Scene2D is no longer an observable. Message sending is managed by the
ViewportController.
Move some refs to shared and weak to prevent lifetime issues.
