Printing a check in the "bottom" position prints the check too low on the page.

In print-check.scm the bottom value is set incorrectly:

    (define gnc:*stock-check-positions*
      '((top . 540.0)
        (middle . 288.0)
        (bottom . 0.0)))

The standard check height is 3.5 inches, which can be calculated from the
top and middle settings: (540 - 288) / 72 = 3.5

Therefore the bottom check should be 3.5" below the middle: 288 - 3.5 * 72 = 36

Indeed, my blank checks begin one half inch up from the bottom of the page:
0.5 * 72 = 36

The code should read:

        (bottom . 36.0)))
