[Lazarus] opengl

[Andrea Mauri]

The example runs correctly under win not under linux.
Under linux I am not able to compile the example project.
I can compile and install the component package and I am able to use the
component under GTK but not GTK2.

GTK2:
new project
I put a TOpenGLControl on a form.
It compiles correctly.
If I run the execution is immediately stopped after the compilation.
