	- made basic marked text highlighting work to complete basic level of <rdar://problem/3704359> input method support not yet implemented for HTML editing

        * kwq/WebCoreBridge.mm:
        (-[WebCoreBridge setMarkedDOMRange:]): Added this new call to support storing

	node, which must be a text node.
        (-[WebCoreBridge markedDOMRange]): New call to get the marked range.
        (-[WebCoreBridge clearMarkedDOMRange]): New call to clear the marked range.
        * kwq/WebCoreBridge.h: Prototype new methods.
        * kwq/KWQKHTMLPart.mm:
        (KWQKHTMLPart::markedRange): Implementation of WebCore call above.
        (KWQKHTMLPart::setMarkedRange): Implementation of WebCore call above -
	store the marked range, and repaint new and old nodes if needed.
        (KWQKHTMLPart::clear): Clear marked range.
        * kwq/KWQKHTMLPart.h: Prototype new methods.
        * khtml/rendering/render_text.cpp:
        (InlineTextBox::paintMarkedTextBackground): New method to paint the background
	for marked text, modeled on paintSelection.
	(RenderText::paint): Optionally handle painting marked text
	background as well as selection background in the marked text
	pass.
        * khtml/rendering/render_text.h: Prototype new method.

	WebKit part of:

	- made basic marked text highlighting work to complete basic level of <rdar://problem/3704359> input method support not yet implemented for HTML editing

        * WebView.subproj/WebHTMLView.m:
        (-[WebHTMLView markedRange]): Use new bridge calls instead of internal marked range storage.
        (-[WebHTMLView hasMarkedText]): Likewise.
        (-[WebHTMLView unmarkText]): Likewise.
        (-[WebHTMLView _selectMarkedText]): Likewise.
        (-[WebHTMLView _selectRangeInMarkedText:]): Likewise.
        (-[WebHTMLView _selectionIsInsideMarkedText]): Likewise.
        (-[WebHTMLView _updateSelectionForInputManager]): Likewise.
        (-[WebHTMLView setMarkedText:selectedRange:]): Use direct bridge call instead
	of private _selectMarkedDOMRange: method, which would now be trivial.
        * WebView.subproj/WebHTMLViewInternal.h: Remove unneeded
