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:
o COIN_PROFILER
o 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 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_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.
