OpenGL pre-3.0: Set the same blend state for all draw buffers (one QBlendEquationArguments) OpenGL 3.0-pre4.0: Set the same blend state for all draw buffers, but can disable blending for particular buffers (one QBlendEquationArguments for setting glBlendFunc, n QBlendEquationArgumentss for enabling/disabling Draw Buffers) OpenGL 4.0+: Can set blend state individually for each draw buffer.
