    Variable NONEConst

    NONE: number

    No scaling happens at all. The canvas is set to the size given in the game config and Phaser doesn't change it again from that point on. If you change the canvas size, either via CSS, or directly via code, then you need to call the Scale Managers resize method to give the new dimensions, or input events will stop working.
