OK try this,,, 1) sbs are intended to be completly seperate to themes 2) a wps is also sort of independant from themes, BUT is made to work with a sbs 3) THE *only* time that the Vi is taken into account is in the wps (which can draw anywhere it likes anyway?
So, get rid of Vi, everything it does now can be done using the setting... *and* we can make it stupidly simple so you cant accidently load a sbs without a viewport setup. after the sbs is loaded it would clear the whole screen, draw once, and stick a crosshair on the screen so the user can draw the viewport where the UI area should go. The only thing that "breaks" is where you want a smaller ui area than the area used in the wps when the sbs is also enabled, which is no problem because the wps needs to be crafted to work with the sbs anyway.
