BooleanautoSizeDetermines if the canvas will auto-resize when the browser window changes dimensions. If true the canvas will automatically fill the window when it is resized.
BooleandontScaleIf set to true, IGE will ignore device pixel ratios when setting the width and height of the canvas and will therefore not take into account "retina", high-definition displays or those whose pixel ratio is different from 1 to 1.
