   // FIXME: The ClipRect passed is in visual coordinates (not flow thread
   // coordinates), but at the same time we pass a fragmentOffset, so that we can
   // translate from flow thread coordinates to visual coordinates. This may look
   // rather confusing/redundant, but it is needed for rounded border clipping.
   // Would be nice to clean up this.
