Previously, all SVG <text> elements were zero-sized boxes, that were only actually positioned and sized during painting. This led to a number of problems, the most visible of which being that text could not be scaled based on the viewBox. Which this patch, <text> elements get a correctly sized layout box, that can be hit-tested and respects the SVG viewBox. To share code with SVGGeometryElement's the PathData (from the prior commit) has been split into a computed path and computed transforms. The computed path is specific to geometry elements, but the computed transforms are shared between all SVG graphics elements.
