SVG Stacking context, an inner node in the layout tree.

https://www.w3.org/TR/SVG2/render.html#EstablishingStackingContex

This is not strictly speaking an SVG2 stacking context, but a looser version of it. For example. the SVG spec mentions that a an element should establish a stacking context if the filter property applies to the element and is not none. In that case, the element is rendered as an “isolated group” - https://www.w3.org/TR/2015/CR-compositing-1-20150113/#csscompositingrules_SVG

Here we store all the parameters that may lead to the decision to actually render an element as an isolated group.
