patch

Fix PDF empty stack offset (/pdfemptycount) in the pattern. Operator scn
depends
on the correct value of /pdfemptycount. This bug was introduced in the rev.
8308.
Comment 3 Alex Cherepanov 2008-04-06 01:02:32 UTC 
The patch is committed as a rev. 8625.
Regression testing shows no differences; we had no files that exercise scn
inside a pattern stream.

Rev. 8626 adds a PDF file based on the sample pattern from PLRM that exercises
scn operator inside a tiling pattern stream.
