    LOK: fast tile rendering (graphics and buttons)
    
    Since embedded graphics and buttons use
    absolute coordinates, we set the origin
    to be the top-left corner of the tile.
    This includes the origin + ScrPos (see
    previous patch).
    
    Then, the coordinates of the graphic is
    shifted by this amount to make sure it
    renders in its relative position to the tile.
    
    This renders embedded graphics and buttons
    at their correct position, with some limitations.
    
    Tiles large enough to cover a graphic object
    show the graphic object where it should be.
    However, rendering a relatively small tile
    doesn't render the graphic. This seems to be
    an issue with moving the graphic's coordinate
    at a later stage than the 2D Processor decides
    what objects intersect with the 'view area'
    that is rendered.
    
    Another issue is that graphs don't render.
    What they seem to suffer is incorrect scale
    and a fix coordinates (they show up as tiny
    thumbnails at the top-left corner and grow
    in proportion to the real graph when resized).
    
    These shall be addressed in a separate patch.

    LOK: fast tile rendering (text only)
    
    For every tile, the bounding columns and
    rows are found. The origin of the device
    is set to the top-left corner of the
    top-most row and left-most column, respectively.
    
    Because tiles don't have to align with a
    column or row, the ScrX and ScrY (Screen Position)
    coordinates are set to the offset a tile has
    to its top-most row and left-most column.
    
    Rendering of text is super fast as the
    minimum area is rendered for a given tile.
    
    However, it doesn't work for embedded objects.
    This is addressed in a separate patch.
    
    One pending issue with text is when editing.
    The text doesn't correctly render while
    editing a cell. This is almost certainly
    because the edit control is not rendered
    at the correct offset (in the middle top
    row it can be seen showing up to the right
    of where it should be).
