Handle Clear* commands for side-by-side framebuffers Clear* commands for side-by-side framebuffers require special handling because only the scissor rectangle of the first viewport is used in the scissor test as defined in the OpenGL 4.1+ specs. To enable clearing of each view of a side-by-side framebuffer all views are iterated over, the corresponding scissor rectangle is set as first, and a Clear* call is made to the driver. Afterwards the scissor state is restored.
