Original change's description:

Fix backdrop_filter_bounds location for clipped layers

Previous to this CL, the location of the backdrop filter bounds
rect was incorrect when the containing layer was clipped by the
viewport. In that case, the offset added to the backdrop filter
bounds transform did not account for the clip. It now does, which
should fix at least four bugs.

Attachment: Bug 1551755 - Don't store a NotSpecified value, use the equivalent None value instead. r?tnikkel

This should not have any functional effects, but it maintains a useful invariant
that the stored field is never NotSpecified. NotSpecified should only be used
as a default value for function parameters, and converted to some other origin
when "at rest" in the field.
