Description Nikolas Zimmermann 2022-11-09 02:45:17 PST 
Consistently use SVGLayerTransformComputation whenever transformations need to be computed in the SVG render tree, utilizing 'TransformState' and 'mapLocalToContainer', which were previously extended for SVGs needs (TransformState::TransformMatrixTracking). This assures that the very same transformation matrices / code paths are used independent if one is using getBoundingClientRect() / getCTM() / getBBox() or when computing repaint rects, layer transform matrices - etc.
