Title:
  Launcher - auto-scroll needs to be more progressive

Status in Ayatana Design:
  Fix Committed
Status in Unity:
  In Progress
Status in “unity” package in Ubuntu:
  In Progress

Bug description:
  When a user enters the scrolling zone at the top or bottom or the
  launcher (both when dragging a icon or with just the cursor) a auto-
  scroll starts.  This auto scroll needs to be made more progressive.
  At the moment the autoscroll is too slow.

  Desired solution:
  - Make the auto-scroll more progressive, e.g. the scroll speed starts slower when the cursor enters the scroll zone, and becomes faster when the cursor is at the far end of the scrolling zone.

  Considering a playback of 30fps, the formula should look like:

  SCROLL_AREA_HEIGHT = 12px;
  speed = (SCROLL_AREA_HEIGHT - mouseY) / SCROLL_AREA_HEIGHT * 30;
