to reduce the churn, we leave the existing constructor in place, and add a clang plugin to detect when the value passed to the existing constructor may contain transparency/alpha data. i.e. we leave expressions like Color(0xffffff) alone, but warn about any non-constant expression, and any expression like Color(0xff000000) Change-Id: Id2ce58e08882d9b7bd0b9f88eca97359dcdbcc8c Reviewed-on: https://gerrit.libreoffice.org/c/core/+/109362 Tested-by: Jenkins Reviewed-by: Noel Grandin <noel.grandin@collabora.co.uk>
