-== Summary ==
-We need to enable users on windows to scroll with pixel level precision (when using a non-discrete wheel), similar to the fine grained level of control that users currently have on OS X.  Windows Vista introduced standard mouse events that contain a higher level of scrolling precision for mouse wheel movement in 2006.  Non discrete mouse wheels have been in the marketplace for awhile now, and mouse drivers are sending these events to applications.
-We're doing this because:
-*Moving to pixel scrolling where possible will make a very common browser activity feel faster, more responsive, and improve the general feel of the application.
-== Team ==
-Who's working on this?
-* '''Feature Manager''': Alex Faaborg
-* '''Lead Developer''': Masayuki Nakano
-* '''Product Manager''': Alex Faaborg
-* '''QA''': George Carstoiu (irc: GeorgeCarstoiu)
-* '''UX''': Alex Faaborg
-* '''Security''': (no security implications)
-* '''Privacy''': (no privacy implications)
-* Etc.
-== Release Requirements ==
-After we land the patch we need enough time for testing, since there is a wide range of mouse hardware out on the market (especially on Windows).
-== Next Steps ==
-Land patch for testing.
-== Open Issues ==
-== Related Bugs & Dependencies ==
-[https://bugzilla.mozilla.org/show_bug.cgi?id=605648 Bug 605648 - Support high resolution scrolling on Windows]
-== Designs ==
-Just pixel level scrolling precision, similar to scrolling in Firefox on OS X.  Currently on Windows we only do line scrolling.
-== Use Cases ==
-"Scrolls like butter"
-== Test Plans ==
-Any and all test plans and strategies.  Either inline or linked to.
-== Goals ==
-The goal is to scroll on Windows as well as Firefox on OS X.  The fact that we only do line scrolling on windows impacts our perceived performance and responsiveness, and the general feel of the application.  Scrolling is something that users do literally constantly with a Web browser (much more than any other interaction or UI control), so changes to how the application scrolls should respectively be prioritized extremely high.  The fact that we don't support an important scrolling feature of Windows that was introduced 5 years ago may be indicative of just how few people at Mozilla actually use Firefox on Windows.
-== Non-Goals ==
-Note that this bug is different than {{bug|590022}}.  Our smooth scrolling preference simply draws 10 frames when we receive an event that the user has moved their mouse wheel a single discrete step.  This project is about fine grained precision, and non-discrete mouse wheels.
