Figured out the easiest way to set a panel to be centered, but a lot of these config things need to be unified and cleaned up.

 TODAY'S GOAL:
 
+* 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
 * Linux on Arch catch2 fails with catch2-main missing and xwayland displays weird when small (gentoo plasma6 wayland).
