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_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
       dont do this by default.

   EnvironmentVariable COIN_ENABLE_CONFORMANT_GL_CLAMP
   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_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 Coins 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 its 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. Its 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.
