Without this patch, when changing the x/y attributes of svg:use, innerSVG and foreignObject, we were relying on the transform changes of the children to trigger the right invalidations. However, changes to those attributes can also change the filter region. And there's a difference between moving children in a fixed filter region and moving the filter region along with the children: In the first case, we wouldn't need to invalidate anything outside the old filter region, because those parts of the children would be clipped away anyway. But when the filter region changes, we need to invalidate both the old and the new filter region. Also, when the filter has primitives without inputs, e.g. flood or turbulence, the filtered frame needs to be invalidate even if it has no children. |
