dnd: Start implicit DnD from the original drag positionwip/carlosg/spurious-window-drags

Locking the DnD actor to the pointer coordinates at the time of
starting a drag (e.g. after the DnD threshold) is going to look like
it lags behind.

Start the DnD operation at the button/touch press coordinates, so
the actor looks like it snaps to that position instead of being dragged
from there.
