Scrollbar

[Ken Ray]

The closest I can come to what you want is:

set the style of sb 1 to "scale"
set the startValue of sb 1 to 1
set the endValue of sb 1 to 3
set the thumbSize of sb 1 to 1
set the pageInc of sb 1 to 2
set the lineInc of sb 1 to 1  -- this is ignored in scales though

The scrollbar has this script:

on scrollbarDrag
  set the thumbPos of me to (the thumbpos of me)
end scrollbarDrag

This sort of "snaps" to the proper thumbpositions, but it flickers as it's
doing so. I'll keep hunting for a better solution, but it would be great if
Rev had a "snapToPage" property (or equivalent) that would take the
flickering away.
