[Q] why is it slow to move complex morphs

Just for curiosity ...
When you move the trashcan, this is a nice and smooth move. But when
you move a complex morph this is quite bumpy.
I once looked at the WarpBitBlt and it did pixel operations in no
time. So I thought: it can't be the foreground pixel moves that use up
the CPU it must be the background.
But this isn't true either, because a plain rectangle moves faster
than a complex morph of the same size.
Why is this ?
