* Allow copy destination to have a different scale from source Will result in more scaled copy destinations, but allows scaling in some games that copy textures to the output framebuffer. * Support copying multiple levels/layers Uses glFramebufferTextureLayer to copy multiple layers, copies levels individually (and scales the regions). Remove CopyArrayScaled, since the backend copy handles it now.
