Some paper facts:

• SS14 Paper supports upto 6 000 symbols per paper. (Including tags) (RMC14 supports 10 000 symbols)
• SS14 Paper can show upto 47 symbols per line. (Does not include tags)
• You actually don't need to close tags for them to work.
• Transparent pixels can be achieved either via [mono], or via [color=#0000].
• You can actually resize paper upto 60 symbols per line! (100% scaling)
• UI Scaling breaks paper rendering a little.

How to use:

1. Get an image (screenshot, extract, create)
2. Crop it (23px horizontal is a recommended maximum)
3. Paste it there (Or open).
4. You can change colors via LMB and copy colors via RMB. (Color picker doesnt support transparent colors, blame Web3 Foundation)
