Switch textures created by DeviceImageFilterProxy to
approx-match.

This revealed some further 0..1 texture coordinate
depedencies,specifically in SkDisplacementMapEffect and
SkXfermodeImageFilter, fixed through use of
GrTextureDomain.

Note: causes minor pixel diffs in pictureimagefilter,
testimagefilters GMs.

Also causes minor pixel diffs in some Blink layout tests,
