/utils/svgTemplates
The svgTemplates utility provides methods for loading and parsing SVG templates.
The utility method is called if the an svg_templates object is defined in either the locale or layer configuration.
Templates may be defined as local files, remote URLs, or data:image SVG strings.
It is recommended to use url encoding instead of base64 encoding for SVG data:image strings.
