        * WebCore.base.exp: Added symbol for capsLockStateMayHaveChanged.

        * page/Frame.cpp: (WebCore::Frame::setIsActive): Calls capsLockStateMayHaveChanged.
        * page/EventHandler.cpp: (WebCore::EventHandler::capsLockStateMayHaveChanged): Added. Tells the focused node's renderer that the capsLockStateMayHaveChanged.
        * page/EventHandler.h:

        * platform/PlatformKeyboardEvent.h:
        * platform/mac/KeyEventMac.mm: (WebCore::PlatformKeyboardEvent::currentCapsLockState): Added.

        * rendering/RenderTextControl.cpp:
        (WebCore::RenderTextControl::RenderTextControl):
        (WebCore::RenderTextControl::paint): Added.  If m_shouldDrawCapsLockIndicator is true, paints the caps lock indicator after the background.
        (WebCore::RenderTextControl::forwardEvent): When the control gets and loses focus, update the caps lock state.
        (WebCore::RenderTextControl::capsLockStateMayHaveChanged): Added. Updates m_shouldDrawCapsLockIndicator, which is true if the field is a password field, 
         and the frame is active, and the element is focused, and the caps lock is on.  Causes a repaint when m_shouldDrawCapsLockIndicator changes state.
        * rendering/RenderTextControl.h: Added m_shouldDrawCapsLockIndicator.

        <rdar://problem/5103625> REGRESSION: Caps lock icon should show in password fields

        * WebView/WebHTMLView.mm:
        (-[WebHTMLView flagsChanged:]): Call capsLockStateMayHaveChanged so WebCore knows it may have to update a password field.
        (+[WebHTMLView _postFlagsChangedEvent:]): Added a comment with a Radar number for why this isn't just in flagsChanged.
        (-[WebHTMLView scrollWheel:]): Instead of calling the next responder explicitly, we can just call super, which will take care of this.
