By doing a little costume trick, I make you zoom infinity! An interesting thing happens after size ~6,100,000,000,000 (6 trillion one hundred billion). Scratch Cat starts to glitch out, and eventually Scratch Cat just turns into a glitchy white mess.
(The minimum size is 1 for everything. Bummer) See inside for script What I did was for the "small" costume, I created one using the "Paint New Costume." At first the resolution is 2x2 (27000), which is already way past any practical use. Then, converting into bitmap makes it 1x1 (108000), which is even crazier. But then, I converted back to vector and then went back to bitmap, giving me that 0x0.
