So all of the special variables that you have in the different configs can easily derived from what you called available_buffers. so: ctx_conf::double_buffer = (mask & BACK_RIGHT_MASK) || (mask & BACK_LEFT_MASK); ctx_conf::stereo = (mask & BACK_RIGHT_MASK) || (mask & BACK_RIGHT_MASK); And the for the buffer selection in ES and VG the semantics are very clear: desired_render_buffer = (mask & BACK_RIGHT_MASK) ? BACK_RIGHT : FRONT_RIGHT; and for GL it pick what it renders to by itself. And if we happen to have a drawable with both back and front that we can always change the st_visual that is attached to the framebuffer.
