9   Enabling profiling in Coin
10       To enable profiling in Coin, use the environment variable
11       COIN_PROFILER. When profiling is enabled, Coin will gather profiling
12       data during every scene graph traversal by any action.
13
14   Enabling the default profiling display
15       To get some profiling data shown on the screen, you also need to use
16       the COIN_PROFILER_OVERLAY environment variable.
17
18       This will give you the default profiling graphics, which shows a top-
19       list of node timings categorized by node types, a scrolling graph of
20       action traversal timings, and a scene graph navigator for closer scene
21       graph inspection.
22
23   Read the profiling data
24       The SoProfilerStats node can be used to fetch the profiling data in the
25       scene graph. If it is positioned anywhere in the scene graph, the
26       fields of the node will be updated every time SoGLRenderAction is
27       applied to the scene graph, with profiling data gathered from every
28       traversal through the scene graph since the last SoGLRenderAction, up
29       to the point where SoProfilerStats is located. Depending of how you
30       wish to use the data, either attach sensors to the fields, or connect
31       the the fields on other coin nodes to the fields on SoProfilerStats.
