  Fix FBO/Texture/renderbuffer class hierarchy issues
  TRAC #14744
  Issue=51/52
  Delegated format queries to RenderbufferStorage.
  Eliminated TextureColorbufferProxy by merging it into Colorbuffer.
  Abstracted texture colorbuffer queries.
  Moved some conversion functions to the right namespace.
  Fixed line-endings in Texture.cpp
