Detect and Compile?

[Shuang He]

Hi,
     Just realized that apitrace may affect code path of 3D application, 
since 3D application may try different ways to probe for supported GL 
extension. One way would be dlsym(), in this case apitrace has all 
possible symbols exported, which will affect behavior of 3D applications.
     Is it possible to make apitrace probe system for supported GL 
extensions, and only export those symbols when building?
     So any thoughts or plan for fixing that?

Thanks
