patch to fix the problem

A recent change to PSOutputDev::tilingPatternFill() causes pdftops to create
much larger files than before.
The change is the test "if (x1 - x0 == 1 && y1 - y0 == 1) return gFalse;".
This causes it to rasterize images that it didn't need to before.
I have a 4 MB PDF file that produced a 7 MB PS with earlier versions of pdftops
but produces a 13 MB PS with 0.18.0.  Patching 0.18.0 to remove the new test
fixes the regression.
