Bug 196458 – Remove legacy webkitRequestAnimationFrame time quirk

• Component: DOM
• Status: RESOLVED FIXED

[Simon Fraser (smfr)]

We should remove m_useLegacyTimeBase from webkitRequestAnimationFrame() (and eventually remove webkitRequestAnimationFrame altogether).

This change will conflict with my patch in https://bugs.webkit.org/show_bug.cgi?id=177484. But this is fine I will resolve the conflict if this patches before mine. Actually this code is confusing and it is good that we are going to remove it.

Maybe this should be logged only once per document per load?

Do we have any precedent for doing this? I thought we usually logged on every call.

    static bool firstTime = true;
    if (firstTime && context().scriptExecutionContext()) {
        context().scriptExecutionContext()->addConsoleMessage(MessageSource::JS, MessageLevel::Warning, "AudioBufferSourceNode 'looping' attribute is deprecated.  Use 'loop' instead."_s);
        firstTime = false;
    }

Ugh, this relies on a static which means it would survive loads and potentially not log when it should.
