to use when scenes have no textures available for some primitives
Since there's no way to determine in advance whether or not a scene
will actually have textures, this prevents the non-ideal situation
arising where no content is shown on the map because we default
to the texture renderer and don't have any textures to draw.
We currently offer three renderer choices:
- Textured (default). Loads the texture image and paints the mesh using
these textures
- Texture color. Uses the center point color for rendering each mesh
triangle. Gives a clear visual overview of the mesh structure while
also providing some context via the texture color
- Mesh. Renders the scene's mesh using a fill symbol
