title: Tick marks don't scale in graphics -- why, and how to fix this?
body: <p>As we rasterize 3D images at higher and higher resolution, every image element should get proportionally bigger and bigger.  However, tick marks stop growing after a while.  Is there a way to ensure that tick marks should grown proportionally to the rest of the graphic, like text does?</p>

  <pre><code>g = Graphics3D[Sphere[], Axes -&gt; True, ImageSize -&gt; 200]
  
  Table[Image[
    ImageResize[Rasterize[g, "Image", ImageResolution -&gt; n 72], 
     Scaled[1/n]], Magnification -&gt; 1], {n, 6}]
  </code></pre>
