This makes sprites' appearance non-deterministic.\r\n\r\n### Steps to Reproduce\r\n\r\nObserve the default Scratch Cat sprite. Run a \"set size to 200%\" block  on it, then run a \"set size to 100%\" block, and notice how the sprite's outlines appear more pixelated.\r\n\r\n![sidebyside](https://user-images.githubusercontent.com/25993062/47574742-47130b00-d90e-11e8-8651-6d509f31c9e0.png)\r\n\r\n### Operating System and Browser\r\n\r\nFirefox 62.0, Fedora Workstation 28 64-bit"}}
