textbackground uses metapost for ALL backgrounds and the default metapost 
code to draw the background (draw_multi_pars, defined in mp-abck.mkiv) 
doesn't handle individual frames. So, you have to write your own metapost 
code to draw the side bar.

Another option for simple backgrounds is to use `\definebackground` 
instead of `definetextbackground`. The background mechanism doesn't have 
too many options, but does honor leftframe and rightframe by default.
