Calling this function will return in a rejected promise (or an error to the callback) if canQueryIcons returns false or no icon could be found for the given name and size.
getIconPathSync(name, size)
Synchronous version of getIconPath.
canQueryIcons(callback?)
Returns a promise that is resolved with a boolean indicating whether calling getIconPath can possibly return results. Will provide the result to the node-style callback, if provided.
canQueryIconSync()
