/**
@method grab -> self
@method grab=( grab ) -> self
Controls grabbing of all mouse and keyboard input for the display.
Grabbing the input is not neccessary to receive keyboard and mouse events,
but it ensures all input will go to your application.
It also keeps the mouse locked inside your window.
It is best to not always grab the input,
since it prevents the end user from doing anything else on their system.
@grab is true or false.
