Bug 46963 – Add helper methods to cast between renderers & SVGTextContent/PositioningElement

• Component: SVG
• Status: RESOLVED FIXED

[Nikolas Zimmermann]

The new text layout engine needs a simple way to cast a inlineTextBox->renderer() to either SVGTextContentElement or SVGTextPositioningElement.
Add static helper methods doing that.

The patch itself looks good to me. r=me with the fixes.

Another name for 'fromRenderer' is maybe more self-explanatory. Niko suggested elementFromRenderer.

The indention is wrong.
