press space to switch costumes this renders shadows by scanning through each pixel of the sprite, and storing in a list if the scanner touched the sprite or not. after this list has been constructed, it then renders a stretched version of the costume with pen, based on said list and the "shear" and "compress" variables. if the list says it touched the sprite at a point, then it will render it in shadow. it's kinda buggy though: it doesn't always get the sprite size correctly, shadow quality doesn't always work well, and the shadow gets warped when it's too far to the right. i'll fix those bugs later
