lower and upper are the bounds of the adjusment, in units
step_increment is the number of units scrolled when using the arrow keys or the buttons on an old-style scrollbar
page_incremenet is the number of page_size units scrolled with the Page Up/Down keys
according to baedert, the other condition is that upper >= page_size, and the effect is that the largest possible value is upper - page_size
TODO so the below is wrong but I'm not sure what's right...
