Add enough information to compatibility-transform getRaw()
Many apps are mis-using getRaw (assuming it means screen-coordinates).
This means, for now, we have to do a compatibility transform on the
API to prevent breaking said apps.
Fortunately, since the input window transform includes rotation,
the only extra information we need to calculate this compat-raw
is the display size.
This CL topic pipes the display size around so that it makes into the
MotionEvent and can be used to calculate getRaw()
