I love UI stuff so this has been fun to play with for a couple of weeks.
I chose to start with Panorama because it's in Source 2 but also it's in CS:GO and and we have access to that via the Garry's Mod license, and I don't think Valve would be pissed that I'm dipping my toes in like this.
I'm avoiding messing too much with the internals because I don't know if this is the exact same code that is in S2, so don't want to end up in merge hell.
