-----------
Backdrop-filter: blur() with a transparent backdrop renders incorrectly.
https://bugs.webkit.org/show_bug.cgi?id=176830
<rdar://34470317>
This sets the 'inputNormalizeEdgesTransparent' property on the CoreAnimation
blur
filter function, required to get correct blur behaviour on the edge of a
partially
transparent surface.
Reviewed by Simon Fraser.
I haven't found a good way to test this that isn't super fuzzy unfortunately.
This is only enabled when unprefixed backdrop filter is enabled, since it
requires
a backdrop root (part of unprefixing) to restrict the blur area correctly.
