New feature: Add icon to tip of gauge pointer #133
You can add an icon (image) to the tip of the gauge pointer with the iconPath and iconScale options. The icon also rotates with the angle of the pointer.
Can I suggest that you add some protection to it before merging? We shouldn't try to draw the image unless @options.iconPath is actually set to something. Just enclose what you added inside an if-block testing if @options.iconPath is provided.
