Automatic alignment of items to an invisible grid, defined by CELLS and CELLSIZE.
Since the grid will be shifted to own a cell that is perfectly centered on the turf, we end up with two 'cell halves'
on edges of each row/column.
Each item defines a center_of_mass, which is the pixel of a sprite where its projected center of mass toward a turf
surface can be assumed. For a piece of paper, this will be in its center. For a bottle, it will be (near) the bottom
of the sprite.
auto_align() will then place the sprite so the defined center_of_mass is at the bottom left corner of the grid cell
closest to where the cursor has clicked on.
Note: This proc can be overwritten to allow for different types of auto-alignment.
