    get rid of more cliprects (readpixel)...

    allow blit path for read pixels if pack->alignment isn't 1.
    
    pack->alignment doesn't matter usually if the image is sufficiently aligned
    anyway. Speeds up some tests/readrate cases by a factor of 100 (since
    the pack->alignment default which noone ever bothers to change is 4).
