Hi,

I just submitted some reftests for the background positioning area and 
background painting area when 'background-attachment' is 'local' (new 
value in css-backgrounds-3.)

Itís the tests whose filenames start with 'attachment-' here:

https://test.csswg.org/shepherd/search/testcase/spec/css-backgrounds-3/load/t120/

They are the tests for my implementation of the feature that is about to 
land in Gecko:
https://bugzilla.mozilla.org/show_bug.cgi?id=483446

Note that two of these tests:
   attachment-local-clipping-color-6
   attachment-local-clipping-image-6

are not exact pixel matches of their reference in Gecko because of 
anti-aliasing. This is managed with the fuzzy() notation that is 
supported by Gecko in the reftest manifest, but might not be supported 
for W3C tests:

https://test.csswg.org/shepherd/repository/tip/contributors/mozilla/submitted/css3-background/background-attachment-local/reftest.list


Also note: Some of the details tested here are not yet in the spec and 
do not yet have WG consensus, but hopefully these tests can serve as 
visual examples and will help the discussion.
