## Notes

### Question 1

This is a packing problem, as described on [Wikipedia][1].
Since this is NP-hard, we know the "exact" solution might be unreachable but we
could find a solution that is good enough for our needs.

### Question 2
### Question 3

## PNG support

I chose to support PNG files through the stb files:
[github.com/nothings/stb](https://github.com/nothings/stb).
I could have implemented basic image support with the PNM format but I think it
is nicer to support common image formats with a simple library.

stb also implements a 2D rectangle packer:
[stb_rect_pack.h](https://github.com/nothings/stb/blob/master/stb_rect_pack.h)
I added this file in the project in order to compare my implementation to
another one.

## 3rd party libraries

I use 2 external libraries for better visualization:
- stb files (for PNG)
- raylib (for GUI)

I don't rely on them for the algorithm implementation and the core of the
exercise doesn't rely on external libraries.
