Processing 116 and direct access to g

Hi there,

There's one thing that has also come up while porting my sketches to 116.

I was using the following code to "try" to force VSync:

Code:


  try{
    smooth();
    ((PGraphicsGL)g).gl.setSwapInterval(1);
  }catch(Exception e){}

But it stops my sketches giving the following error.

Code:

I didn't know if considering this as a bug or an API incompatibility.
