3006966, 3026675, 3071106, and more... (each of these bugs
        has a list of related bugs).

        Needs little more cleanup to correctly deal with non base characters.

        * WebCoreSupport.subproj/WebTextRenderer.h:
        * WebCoreSupport.subproj/WebTextRenderer.m:
        (-[WebTextRenderer drawCharacters:stringLength:fromCharacterPosition:toCharacterPosition:atPoint:withPadding:withTextColor:backgroundColor:]):
        (-[WebTextRenderer floatWidthForCharacters:stringLength:fromCharacterPosition:numberOfCharacters:withPadding:applyRounding:attemptFontSubstitution:widths:]):
        (-[WebTextRenderer _floatWidthForCharacters:stringLength:fromCharacterPosition:numberOfCharacters:withPadding:applyRounding:attemptFontSubstitution:widths:fonts:glyphs:numGlyphs:]):

        Against Darin's better judgement prevent extra layout when not in live resize.  If
        this introduces any regressions I owe darin a good bottle of wine.

        * WebView.subproj/WebDynamicScrollBarsView.m:
        (-[WebDynamicScrollBarsView updateScrollers]):

        Updated to reflect new calling parameter semantic of floatCharacterWidths(),
        which now returns the entire array of widths up the last character requested.

        * khtml/rendering/render_text.cpp:
        (TextSlave::checkSelectionPoint):
