utils.dom.getFastTextWidth() function
Gets the width of a text element using a faster method than getTextWidth. This method requires that we know the text element's font family and size in advance. Similar to getTextWidth, we cache the width we compute.
Signature:
export declare function getFastTextWidth(textElement: SVGTextElement, fontSize: number, fontWeight: string, fontFamily: string): number;
