623766 - Enable smooth scrolling for keyboard and scroll bar interactions

Status: NEW

(Firefox :: General, defect)

Description

[Alex Faaborg [:faaborg] (Firefox UX)]

Previously we had two bugs about scrolling changes:

Bug 590022 - Enable smooth scrolling by default on Windows
Bug 605648 - Support high resolution scrolling on Windows

For mouse interactions, high resolution scrolling is the best approach, but that still leaves interactions with the keyboard arrows, and pressing and holding arrows on the on screen scroll track.

For these actions, we should still display a smooth animation of the page.  We should also stop animating immediately as soon as the user upclicks (either the arrow key or the arrow control).
