Bring the invisible triangle back
This hand-built triangle is in the scene (the renderer even counts it) but nothing appears.
Fix it so an orange triangle shows in the middle of the canvas, and keep the material's default single-sided drawing.
What Check tests
- The renderer draws exactly 1 triangle
- The material is still single-sided (FrontSide)
- The middle of the canvas is orange
