-----------
SVG filter on element below viewport renders spurious black square at
viewport origin
https://bugs.webkit.org/show_bug.cgi?id=314999
rdar://problem/177482001
Reviewed by Simon Fraser.
A CSS `filter: url(#…)` on an element below the initial viewport paints
a black square at the viewport origin.
When the filter target's box doesn't overlap the dirty rect, the
intersection collapses to an empty rect at (0, 0). The next expand()
turns that into a non-empty rect at the origin and the filter runs
there.
Bail when the intersection is empty.
