	- fixed 3117558 -- Assertion failure in KWQKHTMLPart::slotData after typing "amazon.com" twice
	- got rid of the per-part NSEvent in preparation for NSView mouse event handling going through WebCore

        * khtml/khtml_part.h: Added declaration for didOpenURL.
        * khtml/khtml_part.cpp: (KHTMLPart::openURL): Changed name to didOpenURL in the APPLE_CHANGES
	version because calls to openURL from within KHTML need to make the round trip to WebKit.
	Also disabled the "scroll to anchor" part.

        * kwq/KWQKHTMLPart.cpp: (KWQKHTMLPart::isFrameSet): Fix to return false when document is 0.

        * kwq/KWQKHTMLPart.h: Add scrollToAnchor, remove setCurrentEvent and _currentEvent
        * kwq/KWQKHTMLPart.mm:
        (KHTMLPart::openURL): Pass the openURL call to the KWQKHTMLPart.
        (KWQKHTMLPart::KWQKHTMLPart): Don't initialize _currentEvent.
        (KWQKHTMLPart::~KWQKHTMLPart): Don't release _currentEvent.
        (KWQKHTMLPart::submitForm): Pass [NSApp currentEvent] instead of _currentEvent.
        (KWQKHTMLPart::urlSelected): Pass [NSApp currentEvent] instead of _currentEvent.
        (KWQKHTMLPart::scrollToAnchor): Added. Contains the code from the anchor case inside
	KHTMLPart::openURL.

        * kwq/WebCoreBridge.h: Added scrollToAnchorWithURL:.
        * kwq/WebCoreBridge.mm:
        (-[WebCoreBridge openURL:reload:headers:lastModified:pageCache:]): Change around so that we
	don't do a bunch of irrelevant stuff in the page cache case. I think we might just want to
	make a separate method for the page cache case.
        (-[WebCoreBridge scrollToAnchorWithURL:]): Added.
        (-[WebCoreBridge mouseUp:]): Simplify check for nil view. Remove calls to setCurrentEvent.
        (-[WebCoreBridge mouseDown:]): Simplify check for nil view. Fix event type constants for
	right mouse button and other mouse button.
        (-[WebCoreBridge mouseMoved:]): Simplify check for nil view.
        (-[WebCoreBridge mouseDragged:]): Simplify check for nil view.

	- fixed 3117558 -- Assertion failure in KWQKHTMLPart::slotData after typing "amazon.com" twice
	- update NSEvent handling in preparation for NSView mouse event handling going through WebCore

        * WebView.subproj/WebFramePrivate.m:
        (-[WebFrame _loadItem:fromItem:withLoadType:]): Added FIXME comments about matching the _loadURL
	case more closely.
        (-[WebFrame _actionInformationForNavigationType:event:originalURL:]): Only use the event if it's
	a mouse down event. This prevents trouble when we have other kinds of events coming through.
        (-[WebFrame _continueFragmentScrollAfterNavigationPolicy:request:]): Call the new scrollToAnchorWithURL:
	instead of openURL:. This fixes the assertion failure in the bug above.
        (-[WebFrame _loadURL:loadType:triggeringEvent:isFormSubmission:]): Update checks here to more closely
	match the ones in KHTMLPart::openURL that we are replacing. Add more comments.

        * WebView.subproj/WebHTMLView.m: (-[WebHTMLView hitTest:]): Function to intercept all clicks at the
	WebHTMLView level, disabled for now because we are not yet ready.

	- started a gzip download decoder, not yet hooked up

        * Downloads.subproj/WebGZipDecoder.h: Added.
        * Downloads.subproj/WebGZipDecoder.m: Added.
        * WebKit.pbproj/project.pbxproj: Add WebGZipDecoder and zlib.

	- other changes

        * Panels.subproj/WebAuthenticationPanel.m: Fixed screwed-up indentation.
