Projection

• World-space view:

                       x = -visible_width/2        x = +visible_width/2
 y = -visible_height/2  ┌────────────────────────────┐
                        │                            │
                        │          (0,0)             │
                        │            ┼── +x          │

 y = +visible_height/2  └────────────────────────────┘

• Clip-space output:

          x = -1.0      x = +1.0
 y = -1.0 ┌──────────────────┐
          │                  │
          │ Right Hand Ortho │
          │ (with flipped Y) │
          │                  │
 y = +1.0 └──────────────────┘

After projection it gets converted to the actual WebGPU device coordinates (Normalized Device Coordinates):

          x = -1.0      x = +1.0
 y = -1.0 ┌──────────────────┐
          │                  │
          │   NDC (WebGPU)   │
          │                  │
 y = +1.0 └──────────────────┘
