Fixed in v3 (was just in time for that :-) ). >> Signed-off-by: BALATON Zoltan <balaton@eik.bme.hu> >> --- >> For definitions of these see: >> https://learn.microsoft.com/en-us/windows/win32/gdi/ternary-raster-operations > > Comment worth being in the commit description IMO. I don't think adding URLs to the source that can remain the same for years while URLs can go away is a good idea. It's only here to help review.
