Fix SVG clipPath bounding box transform order with objectBoundingBox units
https://bugs.webkit.org/show_bug.cgi?id=304836
rdar://167417135
Reviewed by Simon Fraser.
When a clipPath has both clipPathUnits="objectBoundingBox" and a local
transform,
the bounding box calculation applied transforms in the wrong order. The local
transform
was applied before the objectBoundingBox transform, causing it to be scaled
incorrectly.
The correct order is: OBB transform first (to realize 0-1 coordinates to
pixels),
then local transform (in pixel space).
