            Bug ID: 146345
           Summary: Make JS & SVG animation faster (perhaps do as much as
                    possible in the GPU)
    Classification: Unclassified
           Product: WebKit
           Version: 528+ (Nightly build)
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: SVG
          Assignee: webkit-unassigned at lists.webkit.org

In my current project I animate SVG using JS (JS animation crystallized as the best option). I do ".setAttribute("transform", ...)" or ".setAttribute("x", ...)" (in a requestAnimationFrame loop) to move hundreds of small images fast across the screen (also rotation and alpha).

There might be room for improvement regarding performance; perhaps WebKit/Safari could do as much as possible in the GPU.
