skia2/gm/imagefiltersstroked.cpp
Ben Wagner 7fde8e1728 IWYU for gms.
This almost gets gms to be iwyu clean. The last bit is around gm.cpp
and the tracing framework and its use of atomic. Will also need a way
of keeping things from regressing, which is difficult due to needing to
do this outside-in.
