Yeah, if defined, it is called immediately before attempting input.  This
allows intercepting console messages and such.

Yeah, I looked into this once... and seriously though about using a graphic
object (graphic.js).  Essentially, draw the entire lightbar into two graphics
contexts... one for selected and one for not selected, then use the draw()
method to update the screen.  Wouldn't be all that hard to do,  I just never
got around to it.

Well, since graphic.js is already written, it would actually be pretty trivial.
Basically, the first draw() or getval() called after an additem() would update
the graphical representation... then the draw() function be be from the top
offset to top+height etc.

A single rolling value wouldn't be any better or worse actually.
