OpenMind uses an extension of GLAnimCanvas in order to add it's own functions 
and hide all the low level OpenGL code from the user. 

The new GLCanvas class has been made final and can't be extended ! Why ?

Please, avoid making classes final. This is of no interest for you and prevents the 
end users from making extended / higher level code, which is often very frustrating.

This was done by design. GL4Java allowed two ways of performing OpenGL drawing,
both subclassing e.g. GLCanvas and adding a GLEventListener. OpenGL context
management is somewhat tricky (especially in Java, where exceptions can be
thrown) and has been hidden from the end user in Jogl. In Jogl there is one way
of performing rendering, adding a GLEventListener to the GLDrawable. For this
reason both GLCanvas and GLJPanel are final.
