-		Use GPU rendering to pick a model at the given pixel position.
-		hardwarePick() will check all scene visible meshes bounds against a ray cast with current camera, then draw them into a 1x1 pixel texture with a specific shader.
-		The texture will then be read and the color will identify the object that was rendered at this pixel.
-		This is a very precise way of doing scene picking since it performs exactly the same transformations (skinning, custom shaders, etc.) but might be more costly than using CPU colliders.
-		Please note that when done during/after rendering, this might clear the screen on some platforms so it should always be done before rendering.
