This improves the medicre testing line coverage in nullimageio.cpp from 50% to 95%. * Test writing * Test reading of tiled and MIP-mapped null images * Test setting and reading of attributes * Along the way, identified and fixed a nullimage bug -- it was answering that it supported "rectangles" but had no write_rectangle method. Testing works! Signed-off-by: Larry Gritz <[email protected]>
