Re: [fxtf-drafts] [filter-effects] Require image re-sampling for feDisplacement

@AmeliaBR Making this non-normative makes it harder in the future to actually make it normative IMO. Especially when property and property values are involved. Though we do have at least 2 informative references inherited from SVG 1.1 which say:

> Depending on the speed of the available interpolates, this choice may be affected by the image-rendering property setting.

Do you suggest using this property per primitive or for the entire filter operation? If the latter, then this might interfere if the property actually gets applied on an image together with a filter. So I assume you mean the former.

I'd like to get more concrete into your proposal. Lets say you have a 1000x1000 dot input source and a 1000x1000 dot displacement map. How would the `image-rendering` behave? Scale both up (oversampling) or down dependent on the value of the property? Leave the actual scale level to the implementation? What indication or suggestion would we give implementations? What is the desire of `pixelated`? To get to 60fps animations?
