Make a standard Unity Quad full-screen, purely in the shader

	//
	// 1. Add a Quad in Unity
	// 2. Parent the quad under camera, to prevent frustum culling.
	// 3. Attach this shader.

	/*
	* Used for culling tiles in a map renderer I wrote.
	* All tiles used geometry in the [-1, 1] range, and their mvp matrix would get precalculated.
	* So it was simply a matter of seeing if their projected OBB overlapped with the screen's clip space.
	* Returns true if the cube is visible. (false positives for near misses due to conservative w-value)
	*/
