offscreen-effect: Add a method to get the target area

Browse Source 
The target size is not always enough, there are cases where the offset
used to paint the target must also be available for developers
implementing an OffscreenEffect.

The get_target_rect() method returns the rectangle used to paint the
target, with the offsets in the ClutterRect:origin and the texture size
in the ClutterRect:size fields, respectively.

The get_target_size() method should be deprecated, given that its
replacement is generally more useful.
