-TODAY'S GOAL:
+TODO:
 
+* What's the result of out of memory error with shared/unique ptr?
 * Config is all over the place. Can I get rid of constant.hpp? Or most of it?  Also renderer.cpp:RenderConfig is weird too.  Too much indirection all around.
 * GUI needs to become a statemachine now.  Too many panels open at too many times.
 * Panels should be able to take a width/height and center theirself for me
