    Fixed a recentering after crop/resize bug · 25572c41

    This introduces quite a non-trivial still-point concept... please, read
    about it in the docs for KisImage::sigImageSizeChanged.
    
    The general idea of user iteractions:
    1) When rescaling/rotating the whole image (the actual content
       doesn't change):
    
       -> the scaling/rotating of the image happens around its center
          (not around the center of the screen!)
    
    2) When cropping/changing the size of the canvas (the amount of content
       changes):
    
       -> the content of the image that is left after cropping does not
          change its position on screen
    
    3) When working in FIT_WIDTH/FIT_PAGE modes:
    
       -> changing the size of the image switches zoom mode to CONSTANT
