In order to re-remove the 1-frame input delay, we will have to poll input right after rendering a frame - in other words, just before an input function gets called. To do this, I've added a new function enum type - Func_input - that is the same as a fixed function, but before its function gets called, key.Poll() gets called. And all input functions have been updated to use this enum accordingly.
