#X text 92 291 depth turns on and off depth test (also known as Z-buffering). This is very useful if you are in single-buffer mode \, because then a painting effect can be achieved. In double-buffered mode \, you probably do not want to turn off the depth test \, unless you have taken control of the rendering order by setting the priority of each gemhead (see the gemhead example for explanation).;
