ex.handleResize(text)Keeps a PIXI.Text looking sharp even after canvas has been resized with ex.resize. This function will reset the scale change of ex.resize, and instead resize by changing fontSize instead.
If you use ex.resize, then you need to call handleResize on all Text objects.
This function mutates the Text object and adds new fields to it, which probably will make type checkers fail
text (PIXI.Text): The PIXI.Text object to make resizable.
