Re: [fxtf-drafts] [filter-effects-1] What is the visual effect of filter() on the document element?

I used white for two reasons:

1. The de facto state of browsers is that they use a white background
2. To make the explainer easier to read, so white is also a placeholder

Given that filters can have opacity effects which mix with the UA background color, under this proposal, I also think we should consider just specifying that the UA background color must be white. Though I don't know all the history of use cases this might be defeating. Chrome certainly doesn't allow anything other than white, even when there is an installed theme with another color background.
