Disallow runtime effect color filters that depend on position

Some of these checks are currently redundant (we don't allow color
filters to have children right now). But the next CL will re-add that
capability, and the unit tests here will ensure we don't re-break things
by allowing child-sampling to violate the color filter invariant.
