+    This Compositor imitates the classic forward pipeline used before multi-pass
+    rendering was introduced. It doesn't involve any FBOs and all the rendering
+    happens in two passes rendering directly to the screen.
+    
+    The precision of the Z-buffer deteriorates with huge near-far spreads, so
+    two passes with different depth ranges are used to avoid Z-fighting and
+    other unpleasantness.
