    Remove trailing whitespace

FIlters Added.. again! ...

some filters added to pixi
example 15 added too

Remove trailing whitespace

Changed it so that getBoundingClientRect is called on the new dom element vs the one for canvas

Made the cursor update on the newly set dom element for interaction. Also noticed events were being removed for the current/new dom element and not the old one

Made sure that if the dom element for interaction has been set then the canvas dom element wont reset it

Made it so that you can change which dom element receives mouse/touch events
