DESCRIPTION:The abstract below is from the paper by Igarashi and Hinckley 
 available at http://www-ui.is.s.u-tokyo.ac.jp/~takeo/research/autozoom/aut
 ozoom.htm\n\nABSTRACT\nWe propose a navigation technique for browsing larg
 e\ndocuments that integrates rate-based scrolling with\nautomatic zooming.
  The view automatically zooms out\nwhen the user scrolls rapidly so that t
 he perceptual scrolling speed in screen space remains constant. As a resul
 t\, the user can efficiently and smoothly navigate through a large documen
 t without becoming disoriented by extremely fast visual flow. By incorpora
 ting semantic zooming techniques\, the user can smoothly access a global o
 verview of the document during rate-based scrolling. We implemented severa
 l prototype systems\, including a web browser\, map viewer\, image browser
 \, and dictionary viewer. An informal usability study suggests that for a 
 document browsing task\, most subjects prefer automatic zooming and the te
 chnique exhibits approximately equal performance time to scroll bars \, su
 ggesting that automatic zooming is a helpful alternative to traditional sc
 rolling when the zoomed out view provides appropriate visual cues.\n\nI am
  writing a GUI using pygtk to test the way they propose to implement autom
 atic zooming and scrolling. \nMy (minimal) code as can be cloned from the 
 git repository at\n\ngit://github.com/admg26/scroom.git\n
