GPU Optimization for GameDev

	// With the VK_KHR_maintenance1 extension, you can specify negative viewport height.
	// This allows negative height to be specified in the height field to perform a
	// y-inversion of the clip-space to framebuffer-space transform. This allows you
	// to avoid having to use gl_Position.y = -gl_Position.y, and makes porting to other
	// APIs like DirectX12 much easier.

	// You negate the height and move the "origin" to the bottom left.
	// Unlike the original AMD extension which just negated height.
