Hello all,

I am new to JOGL, so sorry if these are basic questions.

I am searching for a way to find out if the client machine for my program meets a particular set of requirements.  I am using World Wind, which has the following example for their requirements: http://worldwind31.arc.nasa.gov/svn/trunk/WorldWind/src/gov/nasa/worldwindx/examples/OpenGLSupportTest.java

I'd like to not create a frame/canvas to check the functions/extensions requirements.  Is there a way to do this?  I'd essentially like a function based on those requirements that just returns a true/false for requirements met.

Also, in the example, the line "GLCapabilities caps = new GLCapabilities(GLProfile.getMaxFixedFunc(true));" takes at lease 1 second of execution time (which is a large percentage of such a small program).  Could someone explain what this is doing and is this a normal amount of time?
