Hi, today I find this strange behavior: when in the comand `size()` I set the render mode `FX2D` the function `mouseWheel` don’t recognize the count of wheel.

This Example Work fine

```auto
void setup() {
  size(100, 100); // basic comand size()
}
void draw() {
} 

void mouseWheel(MouseEvent event) {
  float e = event.getCount();
  println(e);
}

```

Now I put the render mode `FX2D` and the mouseWheel don’t work:

```auto
void setup() {
  size(100, 100,FX2D); // comand size with render mode FX2D
} 
void draw() {
} 

void mouseWheel(MouseEvent event) {
  float e = event.getCount(); // getCount not recognize the wheel count
  println(e);
}

```

in this last case the local variable `event` stay always at value 0.0

It’s a normal action?

Thanks…
