imageLoad loads the texel at the coordinate P from the image unit image. For multi-sample loads, the
       sample number is given by sample. When image, P, sample identify a valid texel, the bits used to
       represent the selected texel in memory are converted to a vec4, ivec4, or uvec4 in the manner described
       in the OpenGL Specification and returned.
