[Bf-taskforce25] Modal Operators + Moving out of view

[Ton Roosendaal]

Hi,

Iff used properly and according design (modal handler should be on 
screen/window level) the events should get properly handled. I suspect 
this is caused by the recently added "modalops" list, which should be 
replaced. Will check it now.
