We need tests for this change!

This should all be on one line.

We'd usually just put these on one line.

We don't need these braces.

No braces for one-line if bodies.  Also, prefer early return.

Why are we returning zero in both cases?  That seems wrong...

There should be a "Test: editing/pasteboard/data-transfer-items.html" line there (normally prepare-ChangeLog does that for you, but you're probably just editing the previous message).

> Source/WebCore/platform/chromium/DataTransferItemChromium.cpp:112

Should there be a NOTREACHED here?

I'm confused as to what this is for.

> Source/WebCore/platform/chromium/PlatformBridge.h:102
> +    static PassRefPtr<SharedBuffer> clipboardReadImage(PasteboardPrivate::ClipboardBuffer);

Where is this implemented?

Done. For some reason, it's not emitting that line. I added it manually.

It's just a marker to distinguish the overloads of DataTransferItem::create().

I missed reverting this change. Fixed.

Hmm, maybe it only adds it for new tests.  Anyway, it's nice to have either way.

It seems like it would be a bit clearer to name the method createFromPasteboard.  I would probably also just have a single constructor that takes DataSource as a parameter (so you don't have to keep 2 sets of constructor initializer lists in sync).

What is this for?

addPasteboardItem is only exposed to ClipboardChromium.
