            Bug ID: 185758
           Summary: Web Inspector: Canvas: put `hasVisualEffect` behind an
                    experimental setting
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: All
                OS: All
            Status: NEW
          Severity: Normal
          Priority: P2

There is no "easy" way to quickly determine if a particular visual action caused some pixels to change on the canvas, so we have to resort to checking every single pixel.  On larger canvases, this can take a long time, and the problem is compounded if there are a large number of visual actions in the recording.  We should put this behind a setting so that if the user doesn't particularly need/care about `hasVisualEffect` they don't need to suffer the performance hit.
