Copyrights years for new files seems wrong

It is really necessary that all generic graphical menu code like bitmap
scaler works always. Not just for some optimized formats as otherwise it
would render graphical menu unusable in some cases. It can be not so
pretty on low end systems, but it should at least work. That is the
reason there is map/unmap functions in video api.

So there has to be first generic implementation and then you can use
optimized one if there exist one.

Basically I have not bothered to go formats below 1 byte. But obviously
as there is now 1 bit format that needs to be supported too.

Perhaps there should be set/getpixel for bitmap or so. I do not want
those to appear in video drivers thou at least as external.
