No border for compressed cube images

Cube images currently have a 1 pixel border around them for seamless cubemaps. To add a border around a compressed image would require adding an entire block's width/height around the image at each mip level, which would take a lot of extra space and wouldn't be so useful right now, since we'll perform both image decompression and cubemap border update before sampling, so might as well do both at the same time and only store a border in the decompressed image, so that compressed cube images don't need to keep a border.
