The spaces are all too small, and the pieces, not being resized, are cropped at their edges.
Through an oversight it was not specifying a squareSize, and at some point the default for this in the Diagram script was apparently changed to 33 (while it needed 50 to match the piece size and background board image). I fixed that now.
