SVG filter referencing element with huge stroke fails to display
https://bugs.webkit.org/show_bug.cgi?id=304911
rdar://167516452
Reviewed by Mike Wyrzykowski.
The input buffer to feImage may be scaled if it exceeds the 4kx4k threshold;
this happened in the reported
case because of a line with a huge stroke. When this happens, the logic in
`FEImageSoftwareApplier::apply()`
fails to take the buffer scaling into account, rendering just part of the
buffer in the wrong location,
so fix the logic to handle scaling.
