Move render functions to outer deltatime loop

Ok, and this is where the fun starts.

In an ideal world, this would be the end of this patch. However, of
course, there are many, MANY places in the game that update
fixed-timestep timers DIRECTLY inside the render function, which is not
ideal because it means those timers go super fast.

I'll have to fix those later.
