Q: Suggestion: The emoji files should be vectors so that when they are expanded, the quality isn't lost.

In applications such as snap chat where the modification of text and characters is permitted, the emojis take on a very unpleasant look to them becoming very pixelated and distorted. I'm not sure if this issue has been raised yet, but wouldn't a vector file type for the icons fix this? The fonts all have this so why can't the emojis?
