  Refactor how we signal dependent state changes.
  
  Dependent state changes happen when the user calls TexImage
  on a Texture attached to a Framebuffer. The Framebuffer should be
  told 'hey, you should know about this'. Other objects also have
  dependent relationships, like VertexArrays and Buffers.
  
  This refactoring uses a binding pointer design, similar to the type
  'RefCountObject'. This design fixes the need for manual decoupling
  when one or the other is destroyed. The pointers are cleaned up in
  destructors, and do no-ops when either the source or dest is missing.
  
  Also move these new classes to a location where they are accessible to
  the GL layer; they will be important for framebuffer completeness.
