Why I think Immediate Mode GUI is way to go for GameDev tools

Prerequisites

Before you continue, if you don't know what IMGUI is don't bother reading this post, just ignore it, don't write anything in comments section, etc. If you're curious about IMGUI see bottom of this post, otherwise continue whatever you were doing, this post it's not for you. Thanks!

If you know what IMGUI is, for context read following presentations and blog posts:

Insomniac’s Web Tools Postmortem

This is my little Christmas-break experiment trying to (among other things) reduce the amount of generated code for containers.

THIS CODE WILL CONTAIN BUGS AND IS ONLY PRESENTED AS AN EXAMPLE.

The C++ STL is still an undesirable library for many reasons I have extolled in the past. But it's also a good library. Demons lie in this here debate and I have no interest in revisiting it right now.

The goals that I have achieved with this approach are:

	import { FileLoader } from './FileLoader';
	import { DataTexture } from '../textures/DataTexture';
	import { DefaultLoadingManager } from './LoadingManager';
	import { _Math } from '../math/Math';

	function IESLoader(manager) {

	this.manager = (manager !== undefined) ? manager : DefaultLoadingManager;

	}

	void parse_expr(Value *dest);

	Sym *parse_ident(void) {
	if (tok != TOK_IDENT) {
	error("Expected identifier");
	}
	Sym *ident = tok_sym;
	next();
	return ident;
	}

	From metal documentation:

	"Command buffer and command encoder objects are transient and designed for a single use.
	They are very inexpensive to allocate and deallocate, so their creation methods return autoreleased objects."
	https://developer.apple.com/library/content/documentation/Miscellaneous/Conceptual/MetalProgrammingGuide/Cmd-Submiss/Cmd-Submiss.html

	Autorelease example:
	NSAutoreleasePool* autoreleasePool = [[NSAutoreleasePool alloc] init];

	//c is an autoreleased object
