Did a test where I removed all the operators for vec and forced the
user to use functions on the vector instead that mutated the existing
vector.
You had to manually call clone if you actually wanted a new vector.
No automatic copies were done. Expected the performace to increase by
quite a bit since most of the operations are vector operations.
Chaining operations like the following just mutated the existing
vector.
```
vec.mul(vec2).div(2).add(vec3);
```
Could do this pattern for most things.
Turns out is's not such a big deal.
Set up a test case of the simple scene with 3 balls. The difference in
performance was about 1%. Got surprised and made a more complex scene with
over 400 objects expecting to get a bigger difference. Nope. Still 1%.
Decided it was not worth it since it was a bit more annoying working
with the vectors.
Probably get better performance gains with SIMD or using the GPU.

- Was pointless to have one event for render and one for
cancel. Reduced it to one while fixing a minor bug.
- Remove useless dereference and borrow. Not sure how it
ended up like that.
- Moved around some code.

Just wanted to add defocus blur but ended up changing a bunch of other
this as well.
- Moved scenes to a separate folder.
- Updated readme with more pretty images.
- Add interface for loading scenes. There is currently one for yaml
and another if you want a slightly random scene.
- Add image action to decide what to do with the final image once its
rendered. Currently supports just showing the buffer until you press
the render buffer again and saving the image as `png`.
- When you use nix shell you will be dropped in the proper folder so
you can just do cargo build etc without having to do `cd`.

Once the render is done it saves an PNG.

- Made the traits into supertraits so we don't have to mention Send and
Sync everywhere.
- Add methods for Vec3 that modifies the existing Vector. Can be used
to make less copies.

- Created a trait for all geometry that has to implement a hit
function. Depending on if the ray hits or not it returns an option
with the color.
- Add support for multiple samples per pixel
Current issues:
- Using cooperative multitasking which isn't that
helpful in this situation since it's like running without async but
without overhead. Should switch to rayon.
- All data gets copied once per job. Will decide later what to
do (copy or put locks and share data between jobs).
