**Tags:** `3d`

Demonstrates:
  - ShaderMaterial.set_texture() bound to the texture2D the shader declares
  - Separated texture + sampler declarations in the material's own group
  - transparent=True: an alpha-blended custom material over opaque geometry
  - A tiled floor receding to the horizon: the minified half of the mip chain
  - Rebinding a texture on a LIVE material: T swaps all three surfaces to a
    second image mid-frame, and the next frame samples it
  - The same scene rendering identically on the Vulkan and web backends

Controls:
    A / D       - Orbit camera
    T           - Swap the texture every surface samples
    Escape      - Quit

Usage:
    uv run python examples/features/3d/custom_shader_texture.py
    uv run python examples/features/3d/custom_shader_texture.py --test
