V2 hit testing (viz hit testing using cc data) only submits regions with
non-zero origins when the region is clipped by other layers. However, in
these cases, if we offset hit test locations by the "clipped" region's
origin, we will get wrong coordinates for the clipped frame.

Since regions submitted by draw quad data provider can have the offset
factor in the transform, we only disable the offsetting for v2 hit test
in this patch.
