Comment (by jg):

 The code snippet below is from the package libXcursor/src/display.c
 and is the algorithm used to determine the cursor size.

 As you can see, DisplayHeight and Width is used to set a size if
 not overridden by either an X resource or environment variable.

 Kids like larger cursors than adults, so we may want to override
 the default computation.

 This also begs the longer term question of whether we want an OLPC
 cursor theme????

 It also begs the question of whether we've loaded the special high
 visibility themes into our image for those with vision problems????

         v = XGetDefault (dpy, "Xcursor", "size");
     if (v)
         info->size = atoi (v);

     /*
      * Use the Xft size to guess a size; make cursors 16 "points" tall
      */
     if (info->size == 0)
     {
         int dpi = 0;
         v = XGetDefault (dpy, "Xft", "dpi");
         if (v)
             dpi = atoi (v);
         if (dpi)
             info->size = dpi * 16 / 72;
     }

     /*
      * Use display size to guess a size
      */
     if (info->size == 0)
     {
         int dim;

         if (DisplayHeight (dpy, DefaultScreen (dpy)) <
             DisplayWidth (dpy, DefaultScreen (dpy)))
             dim = DisplayHeight (dpy, DefaultScreen (dpy));
         else
             dim = DisplayWidth (dpy, DefaultScreen (dpy));
         /*
          * 16 pixels on a display of dimension 768
          */
         info->size = dim / 48;
     }
