[Bf-committers] Border zoom patch

[Campbell Barton]

are you discussing boarder zoom in perspective mode?
- of course theres no right answer to this one but this may be a good 
solution.

create a plane (tri) that faces  the view and lies on the center point 
(that point you orbit around)
then use the midpoint of the rectangle as a a ray, intersect it with the 
plane previously defined and use that intersection as your new center 
point- after then you can modify the zoom value to make it work more 
like the user may expect- a small rect may zoom in further. - or you may 
find you dont need to adjust that. just moving the camera may be enough.
