Summary: Animations are notified for updates way too often
Product: WebKit
Version: 420+ (nightly)
Platform: Macintosh
OS/Version: Mac OS X 10.4
Status: NEW
Severity: Normal
Priority: P2
Component: SVG
AssignedTo: webkit-unassigned at lists.webkit.org
ReportedBy: macdome at opendarwin.org
Animations are notified for updates way too often
right now animations are notified to update (and thus normally cause a redraw)
30x per second, or something similar *even* if they have nothing to do.
We need to fix the animation notification system to be much smarter.
Animations should be able to register for the next callback at a specific time.
The scheduler could then be smart enough to schedule the timer for the minimum
of all of these. Or each animation could carry a "update after" date, and only
mark it self as needing update when the time passes that date (unless manually
invalidated for other reasons (like applying to an element which needs to
update sooner, etc.)
