Hi Dimitri, could you take a look? 
This change kicks ShadowElement out from <progress>.
I'll do same for <meter> after this one.

Can you explain a bit about the originalVisibility? I may have known but forgotten, and now confuses me. I am easily confused. Why do we need this?

> Source/WebCore/html/HTMLProgressElement.cpp:40
> +class ProgressBarValueElement : public HTMLDivElement {

This class should live in html/shadow/ProgressBarValuePartElement

> Source/WebCore/html/HTMLProgressElement.cpp:53
> +#if 0

You didn't mean to leave this in :)

> Source/WebCore/rendering/RenderIndicator.h:37
> +    virtual bool shouldHidden() = 0;

shouldBeHidden()?

> Source/WebCore/rendering/RenderProgress.cpp:102
> +    for (RenderObject* child = firstChild(); child; child = child->nextSibling())

Why is this here? Why can't we just use RenderProgress:layout()?

This is for the situation that dynamically changes the visibility. (hiding/unhiding the part element.)
Though <progress> has no such case,  <meter> has one.
I'm preparing for code sharing between <meter>and <progress>, so I'll put this here.

Moved to there.

Sure. Renamed.

This is because RenderProgress shares layout() with RenderMeter via RenderIndicator superclass.
I'm going to migrate the layout code of both and remove layoutAsPart() at that change.

ok.

It looks like patch 81031 mis-spells ProgressBarValueElement.h in GNUmakefile.am and WebCore.gypi (ProgressBarValuElement.h c.f. ProgressBarValueElement.h in WebCore.xcodeproj.)

oh, thanks for finding this! I'll fix it before landing.
