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.
