+/** Example 026 OcclusionQuery
+
+This Tutorial shows how to speed up rendering by use of the
+OcclusionQuery feature. The usual rendering tries to avoid rendering of
+scene nodes by culling those nodes which are outside the visible area, the
+view frustum. However, this technique does not cope with occluded objects
+which are still in the line of sight, but occluded by some larger object
+between the object and the eye (camera). Occlusion queries check exactly that.
+The queries basically measure the number of pixels that a previous render
+left on the screen.
+Since those pixels cannot be recognized at the end of a rendering anymore,
+the pixel count is measured directly when rendering. Thus, one needs to render
+the occluder (the object in front) first. This object needs to write to the
+z-buffer in order to become a real occluder. Then the node is rendered and in
+case a z-pass happens, i.e. the pixel is written to the framebuffer, the pixel
+is counted in the query.
+The result of a query is the number of pixels which got through. One can, based
+on this number, judge if the scene node is visible enough to be rendered, or if
+the node should be removed in the next round. Also note that the number of
+pixels is a safe over approximation in general. The pixels might be overdrawn
+later on, and the GPU tries to avoid inaccuracies which could lead to false
+negatives in the queries.
+
+As you might have recognized already, we had to render the node to get the
+numbers. So where's the benefit, you might say. There are several ways where
+occlusion queries can help. It is often a good idea to just render the bbox
+of the node instead of the actual mesh. This is really fast and is a safe over
+approximation. If you need a more exact render with the actual geometry, it's
+a good idea to render with just basic solid material. Avoid complex shaders
+and state changes through textures. There's no need while just doing the
+occlusion query. At least if the render is not used for the actual scene. This
+is the third way to optimize occlusion queries. Just check the queries every
+5th or 10th frame, or even less frequent. This depends on the movement speed
+of the objects and camera.
