can't make the scene if you ain't got the green
So after a couple of days of wondering why every pixel I got handed by
graphics.library was either
0x1 (ie black or so close to black that it might as well be black), I looked at my pixel format setup code and on a whim, removed the stuff where I tried to compensate for SDL and AROS colour component masks being different and used them as-is. This is what happened:
Which I guess means that green is somewhere in the middle and thus coincidentally has the same mask, but red and blue are toast, and my fixup code was totally wrong. Some weeks I’m completely moronic.
