How relevant are power-of-two textures on modern hardware? Put another way, let's say I have a 1050x1020 image. Which is the better practice: to upload it as a 1050x1020 texture, or to pad it with empty texels and create a 2048x1024 texture? Does the answer depend on how many texels I am wasting? (Downscaling or otherwise modifying the image itself is not an option.)
