Overview

This element base class is used for elements that render directly to the Prawn canvas.

Initially when I wrote prawn-svg, I was expecting to have multiple renderers and thought separating the codebase from the Prawn renderer would be a good idea. However, it turns out that the Prawn renderer was the only one that was targeted, and it ended up being tightly coupled with the Prawn library.

This class is probably how I should have written it. Direct render is required to do text rendering properly because we need to know the width of all the things we print. As of the time of this comment it’s the only system that uses DirectRenderBase in prawn-svg.
