...to make it more obvious that, since 63a68064bb33f180b8a231f7524d99405d910226 "make the Color constructors explicitly specify transparency", it should only be called when the argument is known at compile-time to have no transparency/alpha channel. (This revealed a GCC bug causing bogus > xmloff/source/chart/ColorPropertySet.cxx: In constructor ‘xmloff:💹:ColorPropertySet::ColorPropertySet(Color)’: > xmloff/source/chart/ColorPropertySet.cxx:81:9: error: ‘this’ is not a constant expression > 81 | m_nDefaultColor( 0x0099ccff ) // blue 8 > | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~ so in configure.ac suppress HAVE_CPP_CONSTEVAL when the compiler is found broken.)
