    patch 9.2.0965: GTK4: blurry text rendering
    
    Problem:  The GTK4 GUI rounds the character width up instead of to the
              nearest pixel, and adjacent row nodes leave a one pixel seam
              because their boundaries are not snapped to device pixels.
    Solution: Round the character width to the nearest pixel and overlap
              adjacent row nodes by one pixel (Christoffer Aasted).
    
    closes: #21013
