[LBSE] Broaden svgTransformAttributeChangeInducesLayerComposition() to
isRenderSVGContainer()
https://bugs.webkit.org/show_bug.cgi?id=317575
Reviewed by Rob Buis.
svgTransformAttributeChangeInducesLayerComposition() only routed the
transform-attribute fast path through a style/layer recompute for
RenderSVGTransformableContainer, but missed RenderSVGViewportContainer.
(requiresLayer() returns true for isTransformed() and
Without the recompute the fast path took the non-layer transform
update instead, leaving requiresLayer() and hasLayer()
in disagreement and no layer created or destroyed.
Broaden the type check to isRenderSVGContainer(), which covers both <g>
and nested <svg> and adapt the assertion in
updateTransformAndRepaintForSVGAfterAttributeChange() in the same way.
