e shelf - small missing set of signals - tell theme when inset scrolls
the shelf theme actually can't know if there is scrollable content in that direction when a shelf item has autoscroll on and has content in that direction. this is kind of a missing theme capability that is incredibly useful if you want to do certain kinds of themes. this is fairly minor and i'd consider ok for e20 release as we aren't even doing alphas yet...
