Fix reverse bounds calculation for SkImageFilters::Compose
Since reverse bounds calculation is more-or-less the inverse operation
of forward bounds calculation, it needs to be computed from the outer
filter and then the inner filter. Previously bounds were always
computed from inner and then outer, which is only valid for forward
bounds calculations.
