Where is this actually called? Did the patch fail to pick up a changed file? If this is a preparatory patch then the test expectations shouldn't be updated.

This is only invoked if there is an inputEffect, so no need to check this.

FilterEffect::apply()

Florin is correct.  It's virtual, and the base class version returns false.  This patch picks up the override for FEComponentTransfer.

Ah, now I remember how this stupid thing works. Everything defines platformApplySkia but the default returns false. Sorry.

This is a nit. If a reviewer doesn't care then I don't care, but if I were a reviewer I would care having gotten grief about this kind of thing in the past.
