🧹 Refactor rendering & Cleanup

Refactored how the threading worked. Before it just keept up splitting
the screen recursively for x number of times.

Felt like using recursion was unnecessary. It's now just done in a
loop instead. The user can control the behaviour by setting
`num_threads_width` and `num_threads_height` which will split the
image x number of times and run a thread for each.

Split up the rendering function for one that does scaling and one
that doesn't. I just don't want to deal with any kind of scaling when
actually rendering the image. The code shouldn't change much so
maintaining is going to be ok.

- Fixed scaling issues where black bars would appear if the subimage
size wasn't divisible by the scale.
- Cleaned up a bunch of arcs and other things that wasn't neccesary
any more.
