+      Get or set the scale factor in percent for <em>all</em> autocompletion list images. This is useful on macOS with
+      a retina display where each display unit is 2 pixels: use a factor of 200 so that each image pixel is displayed using a screen pixel.
+      The default scale, 100, will stretch each image pixel to cover 4 screen pixels on a retina display.
