Mouse move.

update the current move event's position

see if the pick wanted the move

did, so return

didn't so un pick it

some error checking, so we might have a chance of working :) TODO: nuke this, at some point decide that you are doing the right thing.

if we made it his far, the pick didn't exist or didn't want the event, so just do the standard move.

Mouse down.

see if we picked something

something got picked

make sure picked actually got set

see if the pick wants the event

did want the event, so it was forwarded

didn't want the event, so.. unpick

revert to standard mouse events if nothing was picked, or the pick didn't want the event.
