[Bug 27221] What happens on feImage without valid resource?

https://www.w3.org/Bugs/Public/show_bug.cgi?id=27221

--- Comment #1 from Dirk Schulze <dschulze@adobe.com> ---
The result on various SVG viewers:

Chrome: You see a "missing image" icon covering the top left quarter of an aqua
colored square.

Safari: You see a "missing image" icon covering the top left quarter of an aqua
colored square.

Firefox: You just see an aqua colored square.

Opera (Presto): You see a black square covering the top left quarter of an aqua
colored square.

IE 11: You see a black square covering the top left quarter of an aqua colored
square.

InkScape: Crashes on windows.

Batik: You see a "missing image" icon covering the top left quarter of an aqua
colored square.

Illustrator: You just see an aqua colored square.



All viewers do apply the filter regardless of the missing image resource. But
the behavior is pretty different across browsers.

IE, Opera: Missing image is treated as transparent black.
Firefox, Illustrator: Missing image acts as a null filter even for filter
primitives applied on top of feImage.
Safari, Chrome: General behavior as for IE, Opera but taking the "missing
image" instead of transparent black.
