URLs with trailing punctuation
When a url is posted on a forum/chat, it's often automatically made linkable. But sometimes the regexp that grabs the url also grabs a trailing punctuation mark. For example, if the text is "" and regexp picks up the trailing parenthesis, it will make "" clickable.

And I did use WebGL2, but the improvements turned out to be minor: rewriting Mapgen4's renderer I did need to switch to WebGL2 for features, but implementing those features would make the code more complex and error prone. I decided to switch to WebGL2 so that I could simplify my code. not The Vertex Array Objects and d...
