Example missing reference

What happens if xlink:href of feImage references an invalid or not existing
resource?

The attached example has an feImage element that references a non-existent
image. It is for testing purpose in different browsers.

The test starts with inverting the SourceGraphic color so that we know if a
filter was applied to the element or not.

The it references the not existing image. The test also applies a subregion on
the feImage element.

Then the opacity of the feImage result gets inverted.

Then we composite the previous result on top of the inverted SourceGraphic.
