Bugs:
  Serializer:
    ☐ Do not work in production/uglified code due to classnames

  GPU:
    ☐ Missing pixels when width or height is not devidable by fixed worksize devisor (8)
    ☐ Uncaught in Promise->on heavy GPU frame load
    ✔ Adapt new WebGPU Buffer Spec see: https://hackmd.io/szV68rOVQ56GYzPJMBko8A @done(20-09-01 21:33)
    ☐ Perlin noise random values are now static and not created per texture

  CPU:
    ✔ ImageTexture not working on Firefox due to OffscreenCanvas is not able to use 2d context @done(20-09-11 00:52)

  GUI:
    ☐ Reset to default disable WebGPU -> probably check again
    ✔ When layout is not completely visible (scrolling) with some combinations of resolution @done(20-11-07 17:02)
    

Features:
  Raytracer:
    CPU:
    ☐ Add progressive rendering like on GPU show each sample image
    ☐ Look if Woker logik could be made with comlink: https://github.com/GoogleChromeLabs/comlink
    ☐ Add tone mapping like ACES filmic
    ☐ Add color correction/grading
    Environment Textures:
      ☐ HDR files
      ☐ Open EXR files
    ☐ Add PBR Material (probably Disney Principled BRDF/BSDF)

      ☐ Add motion blur
      ✔ Add textures (solid and checkerboard) @done(20-10-23 23:01)
      ☐ Optional frame seperation like Blender Cycles with e.g. hilbert spiral
      ☐ Cancel GPU rendering
