SVG Composite of Offset filters incorrectly clips https://bugs.webkit.org/show_bug.cgi?id=77660 Reviewed by Dirk Schulze. Source/WebCore: Prior to this patch, when a group of filtered objects was used as input to another filter, the filter only operated on the stroke boundary of the group, and hence excluded the results of filtering elements within the group, or extraneously included regions clipped from the elements in the group. This patch modifies the strokeBoundingBox of SVG container elements to be the union of the repaint rects for the children. This modifes the results returned for sizing filters and for absoluteRects, which will cause inline layout around the group to factor in the resources applied to the group's children. The relevant spec entry is this, in Section 3.7 of the SVG 1.1 spec: "...the result must be as though the paint operations had been applied to an intermediate canvas initialized to transparent black, of a size determined by the rules given in Filter Effects then filtered by the processes defined in Filter Effects." In this case the "paint operations" is implied to include the result of applying "paint" but no resources to the group, which in turn would have resources applied to the children of the group. This makes the most sense, as the current, incorrect behavior makes it extremely diffucult to understand the actions of filters on groups of filtered content.
