-Subject: [PATCH] pdfwrite - undo commit 
- 4dcfae36bb4dcbc4ef3b5e5afc98bcde0d6b9ddc
-
-Commit 4dcfae36bb4dcbc4ef3b5e5afc98bcde0d6b9ddc added detection for an
-SMask when producing PDF/A-2 with ColorConversionStrategy set to a
-device space other than DeviceGray. This was because the version of
-veraPDF at the time gave an error on the SMask data.
-
-It appears the current version of veraPDF does not do so, and nor does
-the Preflight in the current version of Acrobat. I still cannot find any
-authoritative source for whether this is permitted or not. In my opinion
-it should be because the SMask is used as an alpha channel, we do not
-actually draw anything in DeviceGray.
-
-In the absence of any specific documentation, and given that standard
-conformance checkers no longer complain, I'v put the code back the way
-it was before so that we will carry the SMask through in DeviceGray. The
-resulting PDF is conformant according to Acrobat Professional of this
-date (2024.001.20604) and veraPDF 1.24.3.
