-TODOS :
-1. implement :
- * image loading
- * resizing
- * mesh drawing
-
-IDEAS :
-1. Manage device resources with handles instead of having immutable ones in high level resources
- PROS:
- * Allows to manage (swap, create, delete, invalide) device resources easily
- CONS:
- * Can loose track of a resource easily
-
-RESOURCES :
-* SEED Halcyon presentation https://www.ea.com/seed/news/syysgraph-2018-modern-graphics-abstractions-real-time-ray-tracing
-* Cryengine master class https://www.youtube.com/watch?v=34S3onEr3r8
