are going to affect the existing values (what is already drawn).
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.
