Simulate joystick click

[maxsoulard]

Simulates joystick click by calculating if the virtual stick position is
within the canvas circle.
basic example also updated to test the center position.

what about using current callbacks instead ? like here

It is more flexible and let the user chooses the behavior it want for the click

I am not sure to fully understand what you are saying.
As you probably saw, the code I wrote allow to determine if the stick is inside or outside the joystick base circle. I am using that in my app to simulate a stick click (as on physical controllers).
Maybe my pull request naming is not well chosen. Or maybe I didn't understand at all what you proposed :)
