Since the outside thin wall portion undergoes bending deformation, the portion positioned inside the outside thin wall portion to undergo significant bulging deformation upward, and the slope of the top plate portion at the portion where the inside seal projection is formed is increased. The comparator processor checks a meaningful subset of the imaging data generated by the rendering computer for each display refresh scan and thereby obviates the need for the otherwise-required level of rendering computer certification that is impractical or unavailable.
