	- fixed handling of mouse events so I could turn the mechanism on all the way
	- fixed anomalies in the red-painting-for-null-view-detection
	- fixed 3123105 -- REGRESSION: Crash in KHTMLView::unscheduleRelayout on exit
	- fixed 3124047 -- REGRESSION: crash in KWQKHTMLPart::handleMouseDownEventForWidget at nwa.com

        * kwq/KWQKHTMLPart.h: Add setCurrentEvent()/currentEvent()/_currentEvent back, because we can
	end up doing a lot of work and processing a lot of events before we get around to handling the
	current event, so [NSApp currentEvent] won't cut it. Also add clearTimers, passSubframeEventToSubframe,
	an overload for handleMouseDownEventForWidget, and _mouseDownWasInSubframe boolean.

        * kwq/KWQKHTMLPart.mm:
        (KWQKHTMLPart::submitForm): Use _currentEvent.
        (KWQKHTMLPart::urlSelected): Use _currentEvent.
        (KWQKHTMLPart::paint): Fixed red-drawing-for-debug code by using KWQPainter instead of going
	directly to the AppKit level.
        (KWQKHTMLPart::keyEvent): Moved the check for null node up a bit, and set _currentEvent.
        (KWQKHTMLPart::handleMouseDownEventForWidget): Break into two pieces, so we can share the
	code with the new passSubframeEventToSubframe. Set _mouseDownWasInSubframe to false
	when setting _mouseDownView. Use getView() instead of getOuterView() since we really don't
	care about the WebView after all. Use _currentEvent. Add a check for nodes that lack a renderer
	to fix the crash at nwa.com above.
        (KWQKHTMLPart::khtmlMouseReleaseEvent): Use _currentEvent.
        (KWQKHTMLPart::clearTimers): Added. Checks for null view, which fixes the crash on exit above.
        (KWQKHTMLPart::passSubframeEventToSubframe): Added. Checks for the categories of events that we
	can pass to subframes, which are mouse down, up, and dragged events, and passes them along.
	This is the main fix that makes subframes work properly.

        * khtml/khtmlview.cpp:
        (KHTMLView::viewportMousePressEvent): Add call to the new passSubframeEventToSubframe.
        (KHTMLView::viewportMouseDoubleClickEvent): Ditto.
        (KHTMLView::viewportMouseMoveEvent): Ditto.
        (KHTMLView::viewportMouseReleaseEvent): Ditto.

        * kwq/WebCoreBridge.mm:
        (-[WebCoreBridge saveDocumentToPageCache]): Call clearTimers on the part now, instead of the document.
        (-[WebCoreBridge mouseUp:]): Call setCurrentEvent.
        (-[WebCoreBridge mouseDown:]): Ditto.
        (-[WebCoreBridge mouseMoved:]): Ditto.
        (-[WebCoreBridge mouseDragged:]): Ditto.
        (-[KWQPageState initWithDocument:URL:windowProperties:locationProperties:]): Call clearTimers on the
	part now, instead of the document.

	- other changes

        * khtml/ecma/kjs_window.lut.h: Let this be regenerated. I think I accidentally checked
	in an obsolete version of this earlier.

        * khtml/html/html_documentimpl.h: Remove clearTimers(). We don't need it here in APPLE_CHANGES.
        * khtml/html/html_documentimpl.cpp: Ditto.

        * khtml/khtmlpart_p.h: Removed unneeded APPLE_CHANGES. We don't use m_frameNameId any more, nor
	do we need m_savingPageState or m_restoringPageState.
        * khtml/khtml_part.cpp: (KHTMLPart::clear): Removed unneeded APPLE_CHANGES, now that we don't
	use m_frameNameId any more.

        * kwq/KWQWidget.mm: (KWQWidget::getOuterView): Tolerate nil for view here, so we can use this from
        the QWidget destructor.

	- turned on the mechanism that passes events through WebCore, now that it's working better

        * WebView.subproj/WebHTMLViewPrivate.m:
        (-[WebHTMLView hitTest:]): Moved this function in here. Rewrote it. It has a new feature where
	you can set a global and do a normal hit test, needed for the mouse-moved handling below. Also,
	for efficiency, it does the actual hit testing of itself, rather than calling super, which recurses,
	and ignoring the result. The sum total is that it always returns self for mouse-moved events, so
	we pass them all over the bridge at the topmost frame.

        (-[WebHTMLView _updateMouseoverWithEvent:]):
        * WebView.subproj/WebHTMLView.m: Moved hitTest: out of here.
