Detailed Description

       Various aspects of the Coin runtime behaviour can be controlled through setting different
       environment variables to some value. Most of these variables are there for debugging and
       problem-workaround purposes, but a few are for telling Coin where to locate external
       resource files.

       Here we will set up a list of some of the environment variables Coin will check for and
       can alter behavior because of. Scene Graph Profiler The scene graph profiler subsystem
       uses the following environment variables:

       · COIN_PROFILER

       · COIN_PROFILER_OVERLAY

       A lot of other environment variables will also affect the profiling and listing them all
       would be tedious. Most useful is perhaps the IV_SEPARATOR_MAX_CACHES variable for
       disabling caching, and those that disable features like vertex arrays and frame buffer
       objects, but using thise will of course cause you to profile special cases that may not be
       as important as you might think.

   EnvironmentVariable COIN_FONT_PATH
   EnvironmentVariable COIN_DISABLE_UTF8
       Coin from version 4.0 onwards expects all characters related to text rendering to be UTF-8
       encoded.

       This variable should be a set, if you need to reinstate the old behavior of treating all
       characters according to the Western Latin-1 encoding.

   EnvironmentVariable COIN_GLBBOX
       If the environment variable COIN_GLBBOX is set to 1, rendering action traversals will
       apply a bbox action before rendering. This will make sure bounding box caches are updated
       (needed for view frustum culling). The default Quarter/SoQt/SoWin/SoXt viewers will handle
       this at their end (which is the proper way to do it), so we don't do this by default.

   EnvironmentVariable IV_SEPARATOR_MAX_CACHES
       Can be used to tune the number of display list caches stored in each SoSeparator. The
       default value is 2.

       Setting this value to 0 will disable display list caching, and this is often useful if you
       experience weird rendering bugs which are hard to track down.

   EnvironmentVariable COIN_AUTOCACHE_LOCAL_MAX
   EnvironmentVariable COIN_AUTOCACHE_LOCAL_MIN
   EnvironmentVariable COIN_AUTOCACHE_REMOTE_MAX
   EnvironmentVariable COIN_AUTOCACHE_REMOTE_MIN
   EnvironmentVariable COIN_AUTO_CACHING
   EnvironmentVariable COIN_ENABLE_VBO
   EnvironmentVariable COIN_VBO
       Set COIN_VBO=0 to disable VBO rendering in Coin. This is useful if you suspect bugs in
       either Coin's VBO code or in the OpenGL driver VBO handling.

   EnvironmentVariable COIN_VBO_MAX_LIMIT
       Can be used to set the maximum number of items (coordinates, normals, texcoords or colors)
       allowed when creating a vertex buffer object. On most drivers it's actually slower to
       render large arrays with VBOs than with normal vertex array rendering.

       The default value is 256000, and when the number of items exceeds this Coin will fall back
       to normal vertex array or immediate mode rendering.

       See Also:
           COIN_VBO_MIN_LIMIT

   EnvironmentVariable COIN_VBO_MIN_LIMIT
       Can be used to set the minimum number of items (coordinates, normals, texcoords or colors)
       allowed when creating a vertex buffer object. It's a bit of overhead setting up the VBOs
       and the VBO rendering, so we avoid doing this for very small arrays. The default value is
       20.
