Renamed image0TextureSize to imageSrcTextureSize, and removed the other texture-size functions. As texture-coordinates are always in image0's texture texels, calculations with texels are always done with image0's texture texels. Then, other texture-size functions are useless. To avoid confusion, let's remove the functions and leave the necessary funciton.
