+Subject: [PATCH] Fix improper boolean values
+
+jpeg_codec.cc contained some implicit conversions to boolean, which
+is apparently problematic for some versions of libjpeg. Patch
+taken from https://bugs.chromium.org/p/chromium/issues/detail?id=686191
+but not backported, since it has not been accepted into chromium yet.
+
+Task-Number: QTBUG-58482
+
