Update the CRC value in scaling-test.c.

Update the CRC value in scaling-test.c.

The changes in pixman behavior justifying this are:

- New clipping rules

- Bug fixes in region code. In particular, when
  pixman_region_init_rects() is called on these two boxes:

	{ 2, 6, 7, 6 }
	{ 4, 1, 6, 7 }

  it now ignores the first one, which is empty and produces

	{ 4, 1, 6, 7 }

  Previously, it would produce:

	{ 2, 1, 7, 7 }

  for some reason.
