Allow user to build docker images with or without graphics

💡 **Idea**
After merging #133, any Docker image generated from a `Dockerfile` will contain all the required graphic utilities.

Some users may not want to use graphics. Hence, an argument named `withGraphics` could be implemented to indicate during image building time if graphics are desired or not.

Start by locating the Docker image build entry point and the Dockerfile referenced in the issue. Determine how a withGraphics option should select images with or without graphic utilities, then verify that both build paths produce usable images.
