           Summary: REGRESSION: Canvas/reuse:JSHeap got 0.82% worse around

           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Canvas

Platform: mac-mavericks

WebKit: http://trac.webkit.org/log/?rev=167024&stop_rev=167016&verbose=on

Looking at the changes in question I wonder if it is the change to AffineTransform: http://trac.webkit.org/changeset/167017

AffineTransform is used a lot in Canvas. On each save() with a transform we create another AffineTransform on the stack. I could be absolutely wrong though and it is not this particular patch, or it doesn't even matter that much.
