tdf#129916 svx: fix origin of scaled shadow

We assumed that the top left corner is the origin for scaling, but that
is not necessarily the case. The intention is that the shadow direction
can be determined from its x and y offset, and the origin is the
opposite corner of the shape.

(cherry picked from commit e21d522dddce2590ed435890ae8d5fe39658a71a)
