ARB_transform_feedback2

I could not find enough demos on how to use the new ARB transform feedback2 extension. Basically it goes like this,
1) You need to call

 
glGenTransformFeedbacks(1, &tfID); 
glBindTransformFeedback(GL_TRANSFORM_FEEDBACK, tfID); 

like any other function in OpenGL.

2) You specify the buffer and the shader varyings.

 
glBindBufferBase( GL_TRANSFORM_FEEDBACK_BUFFER, 0, tfvbo ); glTransformFeedbackVaryings( pg, 1, attr, GL_INTERLEAVED_ATTRIBS); //(my cards does not support the EXT function

3) In the render function u don’t call glDraw[*] functions instead u call

 
glDrawTransformFeedback(GL_POINTS, tfID); 

The buffer binding is taken from the tfID transform feedback buffer.
Thats it. The new way simplifies the handling of buffers.
Attached is the full source code.
