TODAY'S GOAL:

* Clean up renderer.
* panels and everything except renderer should use character coodinates
* panels should know if they're text vs. grid rendered
* Image -> Text converter.


TODO:
* Keep panel unified by implementing border and backing on grids too.
* Can std::any be defaulted to a noop in the events?
* Save file isn't saving gold.
* Inventory needs to be better, but need some kinds of "weapons" or other loot to get and not just gold.
* Create a few more enemy types to fight.
* Devise a more complete map/world generator that can use the loot and enemies better.
* Maybe an LOS system, but the hearing version works pretty well so far.
* Probably a system for mapping collision types to sound effects, rather than having the GUI do it.

* Write a test that generates a ton of maps then confirms there's a path from one room to every other room?
* Lua integration?

* check out SoLoud.

* BUG: When enemies die they can be overlapping another enemy.
