Customizing GBC images

There are several methods for using images in GBC customizations.

Images for the customization are typically stored in the customization-project-dir/resources/img directory. The `$$RES` variable allows the GBC build process to set the correct path for the resource in your distribution. For example, you can include the following in your scss file:

background: url('$$RES/img/text-color.png')

In this example, the GBC will use the text-color.png image in customization-project-dir/resources/img.
