Bug 76689 – CSS Shaders: Repainting the FECustomFilter requires full source image

• Component: Layout and Rendering
• Status: RESOLVED FIXED

[Alexandru Chiculita]

Because the shader has access to the whole image, repainting a filter chain with a FECustomFilter needs to paint the whole RenderLayer instead of just the dirty areas.

Comment isn't quite correct (and you also only add 0.1 in the test :)

I will also add the tests in chromium's expected results as requiring rebaselines. I want the cr-linux to finish to grab the generated ones on linux.

It seems like the ews takes too long. I've committed with only mac results for now.
