to space widths.  (Sites like www.osnews.com now render correctly.)

        Change word end rounding hack to use ceil of word width.  I'm still noticing a spacing anomaly
        that is fixed by a reload.  Occasionally text runs are still crammed together, but a reload uses
        correct spacing.  This anomaly is often visible on www.arstechnica.com.  Still investigating.

        * WebCoreSupport.subproj/WebTextRenderer.m:
        (-[WebTextRenderer drawGlyphs:numGlyphs:fromGlyphPosition:toGlyphPosition:atPoint:withPadding:withTextColor:backgroundColor:]):
        (-[WebTextRenderer slowDrawCharacters:length:fromCharacterPosition:toCharacterPosition:atPoint:withPadding:withTextColor:backgroundColor:attemptFontSubstitution:]):
        (-[WebTextRenderer _drawCharacters:length:fromCharacterPosition:toCharacterPosition:atPoint:withPadding:withTextColor:backgroundColor:]):
        (-[WebTextRenderer drawCharacters:stringLength:fromCharacterPosition:toCharacterPosition:atPoint:withPadding:withTextColor:backgroundColor:]):
        (-[WebTextRenderer slowFloatWidthForCharacters:stringLength:fromCharacterPostion:numberOfCharacters:applyRounding:]):
        (-[WebTextRenderer floatWidthForCharacters:stringLength:fromCharacterPosition:numberOfCharacters:applyRounding:attemptFontSubstitution:]):

        Tweaks to dragged image.

        * WebView.subproj/WebHTMLView.m:
        (-[WebHTMLView mouseDragged:]):

        Start using khtml's 'toAdd' parameter to justify text.

        * khtml/rendering/font.cpp:
        (Font::drawText):

        Normalize all calls to get width to minimize use of
        ObjC.  Will make it easier to use IMPL cache later.

        * kwq/KWQFontMetrics.mm:
        (QFontMetrics::width):
        (QFontMetrics::floatWidth):
        (QFontMetrics::floatCharacterWidth):

        Pass additional 'toAdd' parameter.

        * kwq/KWQPainter.mm:
        (QPainter::drawText):
        * kwq/qt/qpainter.h:

        Remove methods now that width calls are normalized to single
        method.
        * kwq/WebCoreTextRenderer.h:
