Log Message:
add another Copy8() variant:
- supports unaligned source and destination
- uses all 32bit accesses
- supports copies up to 124 pixels wide so an entire line fits into registers
  and we can ignore x direction
... mostly an exercise in learning how to use the funnel shifter
TODO:
- skip the funnel shifter if source and destination are aligned
- skip fb reads where possible, like straight GXcopy
