-This loop copy as many bits that it can each time, crossing

-successively bytes

-Bit missalignement between src and dest

-We can now get src and align it to dest

-Compute the nb of bit we will be able to copy

-Create a mask that will serve in:

Filtering src

and erase bits where we write, preserve where we don't

-Then write.

-Compute next time cursors for src

-cross boundary ?
