skia2/tests/QuickRejectTest.cpp
Mike Reed 9dc0b9e2f8 remove code now that loopers are dead (w.r.t. canvas and paint)
We can't remove the loopers themselves, as they are still used
by android and chrome (they just don't ever pass them to skia).

Eventually each of those clients will resolve this, but for now
we just keep the classes (and tests) in skia.
