Currently only works properly when filling rects, since that is the only node that implements bounds computation with this CL. Summary of changes: - Scale gradient coords by object bounds when units are kObjectBoundingBox. - Make fGradientUnits protected instead of private. - Change default value of fGradientUnits to kObjectBoundingBox, which is the default according to the spec. - Change SkSVGNode::onObjectBoundingBox to take a full render context instead of length context. - Implement bounds computation for SkSVGRect, SkSVGContainer and SkSVGUse.
