   r = *rect;
   if( vertical )
-    r.bottom = r.top + arrowSize;
+    r.bottom = (r.top++) + arrowSize;
   else
-    r.right = r.left + arrowSize;
+    r.right = (r.left++) + arrowSize;

Are you sure this is what you want?

This will increment r.top and r.left, too!

Even if it is exactly what you intend it to do, then this code is still
confusing and should instead use more explicit notation.
